Senior software engineer. Extensive front end and back end experience. I've spent most of the past four years building AI agents and related system.
I built an open-source, plugin-based agent framework. It supports tools, delegated jobs, knowledge bases, browser and computer control, database access, custom UIs, and image/video workflows.
Lately I've been working on a low-latency, self-hosted voice agent system that uses direct SIP, streaming STT and TTS, Qwen 27B, and vLLM.
I'm also building a browser-based 3D AI character project as a side project. It runs small models such as Gemma 4 and MiniCPM 5 locally through WebGPU. Other recent work include employment verification, medical document processing with complex RAG, browser automation,interactive avatars, and data analysis agent workflows.
Most of my work crosses several layers of the stack. I'm comfortable with frontend and backend web development in Python and Node.js, agent design, model serving, infrastructure deployment. I especially like greenfield projects, though I don't need everything to start from scratch.

I’m an ML Engineer with a software engineering background and an MS in EECS. My recent work has been around deep learning, computer vision and data workflows for real-world ML systems. Before moving into ML, I worked as a backend Software Engineer building payment processing systems with Java/Spring, REST APIs, and SQL databases.
I’m looking for Applied AI/ML Engineer, Computer Vision Engineer, or SWE roles. I’m especially interested in teams building practical ML systems, scalable inference/data pipelines, backend platforms, or applied AI products.
Hi! I'm a pragmatic, product-focused software engineer with 8.5+ years of experience building and shipping web products with React, Next.js, TypeScript, Node.js and shadcn/ui.
Passionate about UX and product design.
In my spare time, I've been working on EasyInvoicePDF - a free, open-source invoice generator.
Co-creator of Mantis (https://mantis-llm-gateway.github.io/case-study/introduction...), an open-source, self-hosted Large Language Model (LLM) gateway that provides a single interface for interacting with multiple LLMs. I was particularly involved with building out the end-to-end asynchronous token streaming pipeline, writing and publishing the SDK on PyPi and automating the deployment
workflow using Terraform.
Senior full-stack engineer & tech lead, 10+ yrs, Python/Django-first. I ship MVPs that reach production and stabilize/modernize legacy systems without breaking what works. Comfortable across backend, frontend, and infra.
Strong on SaaS, integrations and data flows: Zapier apps (Platform/CLI), ERPs, billing, CRMs, webhooks, ETL — plus LLM integrations (OpenAI/Claude). Years spent making systems talk to each other reliably.
Ex-Zapier (integrations), ex-Tesorio. Experience across SaaS, fintech, and e-commerce.
Backend engineer with 18+ years of experience going deep on complex systems to find the highest-leverage improvements. Led greenfield projects from design through deployment at fintechs you've heard of; built payment and accounting systems processing billions of dollars. Wrote the book on integrating Stripe with Rails.

Full-stack engineer, B.S. Math-CS from UC San Diego
I build and run GratMap (https://gratmap.com) a live production web app I designed, built, secured, deployed, and operate solo. React + Mapbox front end, Express/Node + MariaDB back end, on a Linux server I administer myself. Two parts I'd point at: a venue-scoring pipeline that shrinks each venue's median toward the global median in proportion to how much data it has, so a two-report venue can't outrank a two-hundred-report one; and a pre-launch security audit checking for breached-password screening via HIBP k-anonymity, rate limiting, JWT in httpOnly/sameSite cookies, ORM parameterization.
Before that I was the founding engineer at Citmit, a construction-permitting SaaS startup. I joined when they had a product plan and no engineers, built the initial codebase and infrastructure from scratch, and led a team of four through alpha. I implemented Stripe billing, an S3 document pipeline, and the application-side integration for their LLM feature.
I work in Claude Code every day and can explain and debug what comes out of it without it.
I'm a full-stack designer/engineer with a focus on design and frontend working with early to mid-stage startups my entire career taking products from 0 to 1. I've recently been into AI and orchestration and have set up some pretty neat systems and side projects :)

Seeking: Senior Product Engineer with product design ownership (permanent preferred; open to substantial contract work)
I turn unclear product problems into useful, well-designed software. I talk to customers, turn what I learn into product and technical specs, design the workflows and interface, build the system, then help launch, market, and support it. That breadth is my strongest skill: it keeps the customer problem in view throughout.
At Flowstate, I took a workforce-planning SaaS from blank repo to paid pilot in 10 weeks as sole engineer-designer. I currently own product design, backend, mobile apps, Stripe Connect payments, AI-assisted listing tools, and infrastructure for a US trading-card marketplace.
I use and evaluate new AI models and coding workflows to make product development faster, while preserving quality through type safety, tests, CI, review, and product judgement.
I'm looking for a team that uses AI coding tools seriously, values strong product design, and keeps product builders close to customers.
Co-creator of Retriever (https://runretriever.app/), an AWS-deployed observability platform that enables AI-powered trace analysis through distributed systems. Built a custom MCP server allowing developers to query trace data using natural language through LLMs like Claude, optimizing context consumption through intelligent data distillation from verbose OTLP structures.
Experienced with building full-stack applications. I am comfortable using AWS as a cloud environment and have experience with AI technologies such as RAG, MCP, and Vector embeddings.
Technologies: Embedded systems, automotive, machine learning, signal processing, data science, real time computing, safety processes (MISRA, ISO26262, etc), MATLAB, FPGA.
Background: Masters in control theory and signal processing, working in the auto industry for the last 7 years, first on low level powertrain software then the last year or so on LIDAR/computer vision for autonomous vehicles. I've done the most work in C, but I'm now contributing to safety development work with the Rust consortium and Ferrous Systems through my current employer.
Currently doing software defined vehicle software architecture with a focus on fail-safe and fail-operational, loosely coupled, distributed systems. This includes some standards contributions and work with high level suppliers like Nvidia and Renesas for next-generation software/hardware system co-development.
Primary skills include hard real time embedded systems, safety critical applications, firmware development, system integration and complex hardware/software interaction debugging, along with detailed data analysis problems.
Side interests include machining, 3D printing, embedded system development, coffee roasting and furniture making.
Backend/full-stack engineer at an edtech serving 15M students. Built the OCR pipeline processing 10M answer sheets bi-monthly (the company's core revenue product), data pipelines at 100–200K records/day, and LLM/RAG systems in production. On the side I build and ship complete products solo — commitposts.com (AI changelogs: GitHub → changelog page, emails, in-app widget) and clubmint.app. Looking for a remote role at a startup where I can own things end to end.
Senior engineer with 10+ years of experience, while Scala is my strongest language, I'm a generalist and have shipped production code in Rust, Java, TypeScript, Ruby, and more. I'm keen on picking up new tools.
I believe in using the right tool for each task. Strong infrastructure background (AWS, cloud-native, distributed systems). US C-Corp for contracting.
I've attempted to bootstrap products myself so I understand what it takes
beyond writing code. I take full ownership end to end, I don't wait to be
told what needs solving.
Immediate availability because my whole team was laid off recently, I'm used
to work on US timezones. Open to senior IC or tech lead roles.
P.S: I also have decent experience leveraging AI to speed up my work, not vibe coding but holding AI-hands like I'd typically do with junior devs. I also have built multiple AI integrations.

Open to remote contract or full-time work.
Veris — GitHub PR analysis tool that classifies risk and surfaces
a structured merge recommendation with evidence. GitHub App ingests
PRs via webhooks; diffs go to an LLM through OpenRouter; output is
schema-validated before it's ever shown to a user, not rendered
directly. Can reliably check structural consistency, but treats
true intent verification (did the PR solve the actual task) as an
open problem rather than faking it. MVP, live: veris-roan.vercel.app

I avoid abstractions I can't audit. I make product decisions,
not just implementation decisions.
Who I Am: Full-Stack SWE who has proven experience taking a company from a one-person operation to multi-million dollar deals. I'm here for the entire ride, including initial development, product direction, funding, outreach, and scale.
What Makes Me Special: I've got the technical skills, people skills, and industry knowledge that differentiate a successful startup founder from a run-of-the-mill programmer. I love getting to represent my company at conferences, during demos, and in cold outreach, then coming home to grind bug fixes and feature implementations until the sun comes up. I've got the tenacity and dedication your team needs.
Who You Are: A startup in any stage from pre-seed to scale that has a killer product and needs a dedicated technical founder. You have a tight knit team that values one another and helps each another where needed. You're humble, confident, and don't need to one-up each other for the sake of ego. "Don't be evil" and putting people over profit are core tenets of your business model.

I was laid off by Cisco Meraki last summer, where I spent four years as a technical lead for the cloud side of the wireless products. I have experience in both web development and cloud infrastructure roles.
I have worked for years in open source software development. I created and ran two notable open source projects: Lita, a ChatOps framework for Ruby (https://github.com/litaio/lita) which is used by many companies for automating internal operations and workflows, and Ruma, an implementation of the Matrix protocol in Rust (https://ruma.dev/) which went on to become the basis for the official Rust SDK for Matrix.
My ideal role would be building software targeting other developers, either as a member of a developer tools team, or for a company whose products are made for developers. I'm also drawn to companies building "neutral" utilities whose value is fairly self-evident: Things like PagerDuty and Stripe which are generally useful and provide the infrastructure needed for other things to work.
I would love to use Rust professionally, but I'm fine with other languages, too. I'd also be very happy to work on a product with an amount of open source code, given my background working on OSS projects.

I build and run PersonaChat (personachat.chat), an AI character chat platform on Next.js and Supabase — live since 2025, built and operated solo.
Production LLM work rather than demos: streaming chat over the Vercel AI SDK; a long-term memory layer with append-only writes and invalidate/supersede semantics, idempotency keyed on source turn ID so a dropped stream never duplicates a turn; a relationship engine holding state across sessions that feeds back into generation; and the same character system running through a Discord surface, which forced the state logic out of the components into a shared layer.
I also instrument and read my own funnel in Postgres rather than guessing, and I run Claude Code daily against structured specifications rather than prompts — agents write most of the code, the spec and the review are the job.
Open to full-time or contract. Full overlap with European hours, mornings with US Eastern.
SEEKING CONTRACT WORK - Forward deployed engineer, remote, email in profile. Location: West Coast, remote only.
I'm a forward-deployed engineer. My background is 15+ years of data science, but I focus on solving problems. I work in messy, ambiguous, regulated environments. Often at a client's site, inside their systems and their data. I excavate unmapped data, learn how the team works, and ship tools that stay in production.
Deployed and still running today: Legal clause extraction and validation; site corrosion detection and management; routing and predictive-maintenance systems that stayed in service.
I compress engineering, data, and modeling into one function, owned end to end. I show up, figure out what needs to be built, and make it work.
Tooling: ML/AI, LLMs, and the engineering around them: evals, determinism, observability, guardrails. The tech is just a tool, The hard part is knowing what to build.
If you have a messy, ambiguous problem that needs someone who can embed and ship, my email is in my profile.
EDIT: Corrosion detection so people don't think I detect rust code. (Nothing wrong with that though)

My main project is a production CRM built with Next.js/TypeScript/Node: authentication, per-user data isolation, projects and financial tracking, analytics, multi-currency support, an LLM assistant with persistent conversations, CI, automated tests, backups, and deployment on a Linux VPS.
I’ve also built automation/data-processing tooling for 20k+ structured records, worked with REST integrations and Bitrix24 data, and debugged real deployment issues across APIs, SMTP, builds, environment configuration, Nginx and PM2.
I use coding agents heavily, but not as a black box: I inspect the existing codebase, define the scope, review diffs, run type checks/tests/builds, reproduce bugs and verify the result manually before calling a task done.
I’m not looking for a role where “junior” means only converting Figma into components. I’d like to work close to the product and own real problems across frontend, backend, integrations, automation and internal tooling.
Open to full-time work and serious contract opportunities.
Remote: Yes (also open to onsite in Boulder County)

Applied physicist and engineer, 15+ years. Put me on a messy, physical,
high-consequence problem that crosses disciplines and has to ship — not demo.
Recent: 6 years at Agilent building production ML over instrument telemetry —
fleet-wide failure prediction, and a RAG/LLM system for 300+ field engineers taken
from prototype to production (including the confidence logic for when it answers vs.
hands off to a human). Cut data-prep time 8x.
Before that I built scientific instruments from scratch — a fiber-based STED
nanoscope and an OCT microscope — so I know data from the sensor up, not just after
it lands in a warehouse. Earlier: DoD hardware reliability (former TS/SCI), precision
timing, published detector-physics work.
Strongest where software meets the physical world: instrumentation, sensor data, ML
that has to be right because being wrong has consequences. I own problems end to end,
and I'll tell you when the result isn't trustworthy yet.
Open to full-time or contract. Health/medical-device mission a strong plus.
22, self-taught. Won a $100K Meta Llama Impact Grant for Bluai and
presented it at LlamaCon on 2025
Bluai (https://play.google.com/store/apps/details?id=com.bluai.app&...) is a hurricane early-warning app live on Google Play in Mexico,
built offline-first because during a hurricane the network is the first
thing to go. An online RAG pipeline and an on-device Llama 3.2
(ExecuTorch, NPU-accelerated) sit behind one interface, picking 1B or 3B
based on device RAM, so the UI never knows which brain answered. When
everything is down it falls back to Bluetooth/Wi-Fi mesh chat over a
multi-hop wire protocol.
Email me one paragraph about something broken or missing in
your product. I'll build a working prototype and send you the repo plus a
short video of it running, within 48 hours. Free. No call, no interview,
no invoice. If you like it, we talk. If not, you keep the code.
Flexible on compensation for the right team. I'm optimizing for who I'd
be learning from, more than thinking in numbers.
Hi! I'm a fullstack engineer looking for a long-term role where I can tackle challenging problems to help people. I excel at greenfield engineering - turning ambiguous requirements into reliable products.

I'm a serial startup engineer with 15yoe including Rackspace, Rundeck, and PagerDuty. As a full-stack, kitchen-sink site reliability engineer I'm as comfortable running with unsafe pointers as working on React front ends. I look for high impact, ownership, and autonomy roles.
My most recent role was Principal Engineer at HungerRush where I delivered a number of high impact projects, including most recently their next-gen voice AI ordering (OrderAI) platform.
Domain expertise:
- Academic: PhD in mathematics (topological data analysis, representation theory), MSc finance, MSc neuroscience.
- Applied: database proxies/networking, quant dev and backtesting engines, ML/DL for banking & finance (risk/fraud), LLMs and agentic frameworks (tools, planning, eval), image processing, audio processing.
Résumé/CV: available upon request
Systems-oriented ML/LLM engineer specializing in Python/PyTorch and Rust for low-latency, high-throughput services. I have 8+ years of professional experience with Python and machine learning, and 5 years of production experience in Rust.
I thrive at the intersection of complex math and low-level systems. I've worked across multiple heavy domains, with deep experience building high-performance database proxies, modeling financial risk and architecting LLM agentic workflows, alongside applied work in audio and image processing. Actively exploring remote or relocation opportunities where I can apply my deep mathematical background and backend developer skills to hard engineering challenges.
Open to full-time roles or freelance/contract work (able to invoice B2B via my own company).
I have technical depth, good design sensibilities, and I've been building products from scratch at startups or with clients for about 10 years. I've been doing remote contract work for a while now, but I'd like to join a company again and ideally work in-person. Most likely this would be at an early stage startup, but I'm open.
System design is my native mode of thinking. I'm a great person to have around if you're building something where the rules and patterns aren't established and the problems need to be worked through from scratch, whether that's interaction design, architecture or algorithms. I also know React and web technologies pretty well.
I'd been coding for maybe 15yrs before LLMs and agents hit, but I've deeply re-worked how I approach it over the past couple of years. I'm still learning and adapting as the tech develops like everyone else, but working with LLMs and agents is second nature at this point. I've tested the limits, and I've been through the pitfalls.
Senior+ frontend-leaning product engineer with 10+ years of experience. I’m passionate about complex user-facing products where UX, frontend architecture, performance, and business needs are a must!
I led the UI kit initiative that evolved from a DX tool into an important core layer for how the company plans and ships features. It was later integrated into the frontend committee to improve adoption and involvement and to drive frontend development at the company.
I also built various screen-recording tools using FFmpeg and Web Workers, and recently built a tool with Tesseract.js for OCR to quickly understand the screen and recognize patterns, then confirm them with more powerful OpenAI Vision for further processing.
I’m seeking new, complex challenges that require deep knowledge of the client-facing side of engineering, and I'm ready to join as a full-time senior+ frontend product engineer.

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot instances for satellite image processing at Urthecast.
I've managed teams at three companies (up to 6 engineers) and served as product owner for SRE groups, but I'm open to both IC and management roles at the Staff/Principal/Director level.
Looking for: DevOps, SRE, Platform Engineering, or Cloud Infrastructure roles. $200K+ total comp. Remote only, US-based.
Hi, I'm Jonathan, a PhD physicist who moved into infrastructure.
I run infrastructure for an open-source blockchain project where I manage 40+ linux nodes covering provisioning, virtualization, DNS, monitoring, deployments, and user-facing services. I also operate a small web hosting business where I own the full stack from bare metal up. Before this, my background was postdoctoral biophysics and ML research (GROMACS, SLURM, ML-assisted free-energy prediction) plus contract cloud engineering at a startup.
I'm a strong fit for platform, infrastructure, SRE, DevOps, or computational research roles. I do my best work in small, collaborative teams, and I'm comfortable wearing many hats.

I'm an ex-Google software engineer with a PhD in computer science. I excel at technical challenges. Experience all the way up and down the stack, from bare metal, to kernel, to userspace, to desktop apps, to web dev.
Experienced with working in distributed teams.
Looking for full-time, part-time or contract work.
Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.
I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.
Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu
Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.
Summary: Fresher, Just graduated and seeking a job to gain some experience and also want to explore this field a bit more. Can work on any tech stack(preferred Springboot because have some hands-on experience with it). I know how things works so, if I dont know some thing, I can figure it out how to make it work. So please if you have any place or job for me where I can learn and grow, pls let me know

I am strongest in mature or inherited products where a wrong change can break checkout, third-party integrations, application state, or release confidence. My recent independent work includes WordPress/React plugins and hardening sandbox and proxy behavior for an AI app builder.
Open to full-time, contract, part-time, or short paid stabilization work. Available immediately.
Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice.
Due to high interest in my work with recursive self-improving coding agents, I've shared an example repo at https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows.
I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering and complex frontend architecture.
Notable projects include custom legal document management dashboards and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across fintech, streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments.

Senior Software Engineer with experience building and scaling real-world financial systems at Nasdaq. Worked across the stack with Java/Spring Boot, React, and SQL to deliver high-performance trading infrastructure and leading onboarding for billion-dollar enterprise clients.
Strong foundation in mathematics (BSc from the University of Toronto) with a deep interest in data structures, algorithms, and computational theory.
Comfortable owning features end-to-end, collaborating and building scalable, reliable software. Looking to contribute to solving complex, high-impact problems.
I'm a Product Engineer and a creative based in London. I’ve built full-stack applications across web, mobile, blockchain and embedded platforms. My client-side work includes React, Electron, Roku’s Scenegraph, and native iOS development with Swift and SwiftUI, always with a strong focus on UX and design-first thinking. On the service-side, I’ve worked with traditional service hosting, containers, and serverless, including (but not limited to) AWS, GCP, Cloudflare, Workers, CloudFormation, SAM CLI, nodejs, bunjs, MySQL, Postgres, NoSQL, grpc, Redis, Docker, nginx, and a few legacy tools best left unnamed (yes, including CodeIgniter and ftp).
I’ve also developed developer tools like CLIs and SDKs, primarily Typescript/JavaScript land, and have written code in systems languages such as Rust and Zig.
I care about great UX, developer experience, documentation, rapid iteration and automating workflows with CI/CD (GitHub Actions, Bash scripts, etc).
Also familiar with modern development practices by leveraging coding agents, such as pi, opencode, claude and LLM, including kimi over fireworks inference.
I founded a real estate development+proptech company, exited an 8-figure gdv residential project and recently sold a decision-support saas for new-development underwriting.
Before that, I did ML research (session-based recsys, re-reranking, model selection optimization), product management at an early-stage vc, and built other end-to-end full-stack AI products that helped real estate brokerages and developers automate more than 150 hours per month in manual research and analysis workflows, more than doubling their project throughput.
I’m a senior engineer and software architect used to working with teams that are starting to strain under growth, complexity, or delivery pressure.
Over the last ~10 years I’ve been working with startups and established companies, primarily in roles where I take end-to-end technical responsibility: from system design through implementation and production operation, while remaining hands-on in delivery.
Recent work includes leading the architecture, implementation, and operational ownership of a distributed platform for venture capital workflows, as well as building and maintaining a survey fulfillment system. Both engagements included mentoring and coordinating engineers alongside delivery. More details can be found at https://robinsiep.com.
I'm currently interested in finding a more permanent role, but remain available for contract work in the meantime.
Operations engineer (20 years in ERP) — I fix messy business operations with AI and automation. I take a messy task description and turn it into a technical plan and working code fast. Recent work includes production ERP extensions delivered in days, AI-assisted document automation, Telegram workflow bots, and automation pipelines for business operations (code samples: https://github.com/Aleksandr-Gorbatov/automation-kits). Looking for part-time contract or project work. I work best in async, written communication.
I build LLM systems that run in production. The clearest example is live: pick a sector at https://demo.consentleads.uk and message it the way a customer would. Nothing is scripted. It runs on a free-tier ARM box behind a Cloudflare tunnel, is multi-tenant and has users, and nine scheduled jobs keep it going unattended.
If opt-out detection misses a phrase, the system keeps emailing someone who asked it to stop, and nothing crashes or alerts. So the suppression gate fails closed, and the eval fixtures cover that path and reply triage.
I also wrote claimcheck (MIT, https://github.com/visione4906/ctaio-claimcheck): give it a document and a codebase and a second agent has to prove every claim against the source with file and line citations, or the build fails. I built it after an outside review of my own writing turned up claims the code did not support.
Looking for AI engineering or AI automation work, remote.
Expert backend developer primarily focused on data engineering, mission critical/low latency/highly available systems, and AWS (certs: https://www.credly.com/users/jon-north.ad78f0c8). Happy to deal with greenfield or legacy or any mix of the two. I learn new things extremely quickly.
I prefer long term contract work, though I’ll help you with smaller things as well. W2 employment is a possibility if the fit is right. Whatever you’re doing with AI is also fine by me, and I’ll lead/adapt as appropriate.
Full-stack engineer with 20+ years of experience, looking for a founding or first-engineer role. I build products from scratch and can work across frontend, backend, mobile, and infrastructure.
Particularly interested in small teams where I can take ownership and ship complete products.
Based in Georgia and accustomed to working US Pacific hours.
Senior iOS & Product Engineer with 18+ years of iOS development and 20+ years of software engineering experience. I’ve led development of award-winning apps featured by Apple, The New York Times, and Forbes, and have worked remotely with distributed teams for over a decade.
I’m looking for Senior/Lead native iOS roles where I can own product quality from architecture through implementation, with a strong focus on performance, user experience, and shipping polished apps.
Systems Engineer, looking for any infrastructure or software engineering work. I've worked on all sides of the stack building internal web apps, CI/CD pipelines, observability traces/dashboards, and ML research platforms. I'm a very curious and fast learner who loves to dive deep into unfamiliar environments. I would love the opportunity to build something new at your company!
Software Engineer and recent Computer Science graduate (Math minor) with hands-on experience co-founding initiatives and shipping full-stack applications. Tech stack includes FastAPI, React, TypeScript, PostgreSQL, and familiarity using Linux environments.
Interested in full-stack, backend, or systems-focused software engineering roles where the focus is building functional, reliable products and APIs. Open to full-time remote or onsite opportunities.
I started as a fullstack JS engineer and grew into product development at my last company. I owned the ingestion layer - collecting 100k relevant messages/month from 4 platforms through a dirt-cheap serverless back-end on Cloudflare Workers.
We worked with LLMs deeply, especially in code generation. I was part of a small team developing SpecGEM, a fine-tuned model that generates Cloudflare Workers code from JSDoc comments and is designed to outperform mainstream LLMs at this narrow task.
I just released an open-source self-hosted LLM assistant on Cloudflare Workers that predictably compounds context across conversations. https://github.com/kol3x/pawmc
Looking for a remote role where I can own work end-to-end. Stack-wise I'm strongest on Cloudflare Workers, JavaScript, and practical LLM integration.
4+ years of xp. Started out doing systems and backend programming but I've spent the last few years doing product development for very modern app stacks.
I'm more than happy to learn a new language or two. I've worked with AI since 2018 at a variety of startups, but I'm equally comfortable with non-AI work.

Developer with 26 years of experience who's just been told he can't progress because he's "indispensable" in his current role. I'm looking for a role as a team lead or similar, a career path beyond individual contributor. Deep knowledge and experience with many tech stacks.
Final-year CS student and backend developer with a systems-programming leaning. I like working with backend systems, More than that I am eager to learn from anyone. Apart from my coursework I have worked on - crawlers, TUIs and rate-limited APIs.
Open source / recent work:
Contributing to the Linux kernel - submitted patches to drivers/staging/rtl8723bs/ (checkpatch cleanups), currently working through review feedback with the maintainers.
Built web_weaver, an async Rust web crawler from scratch: tokio-based concurrency, per-domain rate limiting, robots.txt compliance, SQLite + FTS5 storage, crawl resumption via a persistent queue. First of a planned three-part research/search tool.
Comfortable across the backend stack: Go and Rust for services, Postgres/Mongo for storage, some exposure to Elixir and Zig.
Based in India (IST), but can shift my hours to get a solid 3-4hr overlap with EU or US mornings - happy to discuss specifics.
Looking for a remote backend or systems-adjacent role at an established company or a startup with real funding/traction/team - not a pre-idea-stage solo founder project or a "let's see if this works" 3-month gig. Open to relocating for the right role if the company is based in India.

Senior software engineer, experienced with backend engineering, databases, data analytics, application security, web applications, and fullstack development.
I’ve spent about half my time in first/founding engineer roles at startups, and half working directly for clients, agencies, and institutions on a wide variety of products. Folks enjoy my enthusiasm for their ideas and my ability to meet them where they are technically, always providing that extra context that builds trust and understanding.
I’m comfortable owning concerns end-to-end, from initial scoping and architectural tradeoffs through deployment of functional prototypes and user testing. I enjoy iterating and scaling systems from there, while building teams to maintain and build upon them.
Expertise in database design, media rendering systems, engagement platforms, high-volume event ingestion, ML pipelines, and getting it all working in AWS. Top priorities are data integrity, security, and privacy.
Lean on me for:
- Technical scoping and planning for a new product or platform before committing resources
- Architectural review and data modeling to see how a system should flow and which tradeoffs matter
- Greenfield builds where you need someone to plan and ship v1 without much hand-holding
- Forward-deployed engineering, working directly with potential customers to help guide the product
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.
Data scientist with 4+ years of experience delivering production machine learning solutions to top pharmaceutical laboratories. I am able to use LLMs intelligently to create novel models with qualitative accuracy, where LLMs alone would make something that is accidentally correct at best. I have the aptitude for iterating fast in a startup environment, I was able to deliver a working product years before our closest competitor and those models have prevented millions of dollars in losses in the past 3 years with more to come.
Looking for data scientist and machine learning roles
Heya, I am a developer with 4+ years of experience working with React, Next.js and node.js. I have written some blogs about things I built.
I am always up for learning new things and applying it,if you are looking for someone who can be in your niche tech or something challenging,Then I am your guy.
Other than that, I love movies and books, mainly stories, world building, fantasy, and that would be awesome if I got a chance to work on anything in this

Senior Ruby/Rails engineer, 11+ years. My specialty is data-heavy Rails: making it fast, and making it correct.
- Partitioned PostgreSQL at scale — ~330M rows / ~220GB in production, entity resolution and duplicate-merging across 100M+ row tables
- Query performance — 5–40x speedups by restructuring schemas and moving hot paths off Postgres onto OpenSearch
- Billing engines — rebuilt one for ~10x faster calculation and ~50% smaller database (ActiveRecord→ROM), another for a 5x speedup on the bill pipeline
- Recently — pgvector/RAG inside Postgres, LLM integration in Rails (RubyLLM, MCP tooling)
Likely a good fit if you have a Rails app outgrowing its database, a billing or usage-metering system that's slow or subtly wrong, or you want RAG without bolting on a separate vector DB.
Open to full-time or contract. 4+ hours of daily overlap with US East now; the Lisbon move in November adds 2 more. I invoice through a registered sole proprietorship with a W-8BEN on file — no US withholding under the treaty, nothing for a finance team to set up.

I train small language models from scratch and ship them into production myself - on a single 8-year-old Quadro GP100 workstation, no cloud spend.
- RustMind: a complete LLM training stack written from scratch in Rust on Burn - model, byte-level BPE tokenizer, corpus pipeline, GPU training. Ladder from 21M to 125M; the 21M encoder is trained to production quality and ships in
software today. Public pipeline proof (MIT): https://github.com/IsaacLevinsky/rustmind-mini-embed-base
- Root-caused a generation-collapse failure to non-stratified validation splits and over-memorized templated data, then rebuilt the corpus pipeline around document-aware chunking.

Native application development for iOS, Android, Mac and Windows with over a decade of experience. Creating and/or integrating APIs/SDKs. TV/Video applications on all platforms (Apple, Android, Amazon, Roku.) Extensive experience building products and platforms from the ground up.
Senior Software Engineer with 7+ years of experience building scalable backend systems, AI-powered applications, and cloud-native platforms. I specialize in AI agent orchestration, distributed systems, cloud architecture, and full-stack development, with extensive experience integrating LLMs into production workflows and delivering high-performance software solutions.
I build the tool layer that agents call, and I've had one in production long enough to know where it breaks.
At Chronicle I built our hosted MCP server end to end — eight tools that Claude and ChatGPT authenticate into over WorkOS OAuth with JWT and async polling, running on ECS. Also our first public REST API and the developer docs, a workspace-scoped API key system for tenant isolation, and an npm node that had to pass n8n's strict-mode security review before listing. On the interface side, an AI-generation UX with streaming tool-call visualisation, cancel/abort mid-flight, and live document editing over CRDTs.
What I've learned is that agent failures are boring and specific rather than clever. I lost four days to what looked like an auth error and turned out to be a tool declared without an input schema, silently changing the signature the SDK used to call my handler. Four theories before I read the error string properly. I write the theory down before chasing it now.
I also shipped Recall (https://recallapp.online) solo in about two weeks — notes into flashcards over MCP, with FSRS scheduling. Design, backend, payments and launch were mine. #22 on Product Hunt. Before Chronicle I owned a Shopify-to-custom-platform migration end to end, including ingest pipelines from three sources into Postgres.
~4 years. Looking for a remote backend, full-stack, or agent-infrastructure role where I own things end to end rather than picking up tickets.
Open to full-time or contract.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.

About: I am a Generative AI Engineer who also happens to be pretty hands-on across the full stack development. Most of my recent work has been building RAG pipelines, AI agents, and natural language search — using LangChain, LangGraph, and vector databases like Pinecone and ChromaDB — with OpenAI, Anthropic, and Gemini APIs under the hood. I care deeply about shipping GenAI features that hold up beyond the demo stage.
Beyond GenAI, I am working on the full stack — React/TypeScript on the frontend, Node.js or ASP.NET Core APIs on the backend, and AWS/Azure for infra. I like owning things end-to-end and building software that's simple and reliable.

Open to both short/long-term contract or a full-time position if the chemistry is there.
I fluctuate between:
- Deep learning / Neural networks - from architecture to inference. You might have used my ♥ Lovely Tensors library if you work with PyTorch (or JAX). Some CUDA, pytorch profiler, etc.
I built and operate a 106k+ LOC production SaaS on Next.js 15, Supabase and Stripe — solo. Zero "any" types in the whole codebase, 743 passing tests.
What I'm actually good at is the part that breaks after launch: the webhook replay, the downgrade that never revokes access, the export gated only in the browser, the URL fetch that can reach your metadata endpoint. I've put my own codebase through repeated adversarial audits and can share a redacted report — real findings, real severities, subject anonymised.
Available ~20-30 hrs/week, UTC+0 — good overlap with European hours and US mornings. Contract or fixed-scope. I also do fixed-price pre-launch audits (security, billing correctness, data exposure) if that's more useful than hourly.

Defensive platform security engineer available immediately for contract or full-time work.
Experience includes Linux kernel hardening, seccomp, container isolation, NGINX/TLS, CI/CD security, Windows endpoint controls, and Android/AOSP platform security.
Best fit: platform security, infrastructure security, Linux systems security, container security, or Android/AOSP engineering.
WHAT: Whether human or AI built, I know how systems break. I build them so they don't. After three decades of battle-tested experience there isn't a failure mode I don't know how to fix. When it comes to AI, I design and architect systems using my own rigorous engineering approach that insures consistent delivery and drift control.

** Custom architecture & development for startups and specialised cloud models
I work with companies and teams who honestly want to deliver the best product they can. I'm serious about my work and I work only with equally serious people. If you want systems built right the first time, I'm your guy.
Software Engineer with 3+ years of experience building frontend applications, backend services, automated testing pipelines, and AI-powered developer tools.
At my current company, I've improved Angular applications, built Spring Boot microservices with 100% unit test coverage, automated Playwright regression testing (reducing execution time from 2 hours to 30 minutes), and developed an AI-powered MCP server that generates Playwright tests from natural language, reducing test authoring from 45 minutes to under 2 minutes per spec.
I enjoy building products end-to-end rather than working on isolated tickets. Recently I've been focused on AI developer tooling, RAG pipelines, MCP servers, and LLM-powered automation alongside traditional backend development.
Some highlights:
• Spring Boot microservices and REST APIs
• Angular, React, Next.js, Node.js
• AI Agents, MCP, RAG pipelines, vector databases
• Playwright automation and developer productivity tools
• AWS, CI/CD, SQL
I'm looking for a remote backend, full-stack, or AI engineering role where I can own features, work closely with a product team, and build software that ships to users. Startups and product companies are especially interesting.
If you're looking for an engineer who enjoys solving problems, automating repetitive work, and shipping production-ready software, I'd love to talk.

I'm looking for monthly/yearly "no-strings" sponsors, not employment, if any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me (see HN bio).
I build data pipelines that know when they're lying to you.
GAScout (https://gascout.pages.dev) — Georgia public-records pipeline. Four counties live, each a different ingestion problem resolved into one schema: a 9,915-page fixed-width mainframe PDF (409,142 records, zero dropped rows), a weekly XLSX roll, monthly text PDFs, and scanned sheriff's levy documents via OCR. Adding a county is a config file, not code. The other 155 are labeled planned rather than filled with invented numbers.
FindStorage (https://findstorage.pages.dev) — national self-storage pricing tracker. 4,639 locations, 245,000+ price changes logged, running unattended on a daily schedule. Aborts rather than publishing when the store count moves more than it should, because the failure that costs you isn't a crash — it's a scraper quietly returning less after a site changes and nobody noticing for three weeks.
Also built a WiFi CSI device-fingerprinting array on ESP32 — custom ESP-IDF firmware and a Python DSP pipeline, running as my apartment's security system. Cross-manufacturer separation holds at 11-15 sigma; same-model discrimination tops out near 77% and true clock twins are the open problem.
Before this I ran a 500-acre motocross park in Northern California: acquired dormant land, re-entitled it, directed a 120-person race-day crew, ran the medical plan through a mid-event helicopter evacuation, and sold my stake.
Self-taught, ~18 months in. Interested in data engineering, pipeline work, and anything where messy real-world sources have to become trustworthy structured data.

I'm Jeff, an experienced developer with pretty broad experience. I've done things like robotics control software and video processing software, all the way up to scalable enterprise applications and big-data ETL automation. In my free time I write games, language runtimes, and hack the NetBSD kernel for fun. I freakin' love to program, and I love crafting straightforward, effective solutions that serve the user.
Ava, a real-time captioning platform for one-on-one and group conversations, online and in person. 11+ years, zero to product. I co-founded it and was CTO, but the backend was mine throughout, first building it and later as Backend Lead. What that covered: the live captioning pipeline, where latency, accuracy, and reliability all had to hold at once. Drove the backend from a monolith into a monolith plus microservices plus serverless, over an event-driven layer, to keep service stable. An observability stack with Prometheus and Grafana, built from scratch. A datastore migration across 100K+ accounts with no downtime, running both databases live instead of taking a batch window. The subscription and enterprise licensing backend behind customers like Disney and Nike. Penetration test remediation three years running across four teams. On call for all of it. None of this was a fresh start. Everything was already running, with real users on it, and it had to keep running while I changed it.
How I work: most of what I've built started as a vague idea, and my job was making it specific enough for other teams to build against. I own my scope end to end, and once people start building, the spec always changes. That back-and-forth is where the design actually gets figured out.
Two projects I'm working on now:
Clearway: audits websites for accessibility and drafts the compliance report a specialist would write by hand. False alarms 43% to 23%, real issues caught 74% to 83%. My first AI reviewer scored well on my own gold set and near zero on the external W3C one, because it shared a rubric with the drafter. A second reviewer reading independently now catches 53% of those errors. Small-sample measurements, not proof.
VOX Personalis: fine-tuned Whisper with LoRA on my own Deaf-accented speech, because no off-the-shelf ASR handles it. WER 238.69% to 34.05%, now with sub-second streaming output. Next is sub-20% and on-device.
Communication style: I'm Deaf and work best with text-first collaboration, clear written specs, async updates, and captions/transcripts for meetings. This is how I've worked for 11 years, including with enterprise customers.
Looking for: Senior Backend IC, MTS, or Founding Engineer scoped to backend and agent infrastructure. Seed to Series B, applied AI, SF onsite or hybrid, full-time. Going deeper, not wider. I want to put a deep backend foundation to work on the part that’s hard: making a service reliable on top of an LLM that isn’t deterministic.
I build the systems plumbing, concurrent pipelines, and secure runtime isolation that AI coding-agent startups are racing to ship. Happy to prove it directly on your codebase first — I'll take on a 2-3 week paid trial sprint on a real backend bottleneck before any longer-term conversation.
• AutoPatch-AI (https://github.com/sriramvarun0636/AutoPatch-AI): Autonomous, self-healing code remediation agent built on a LangGraph state machine. Engineered a zero-trust Docker execution layer (network_disabled=True, 256 MB RAM / 128 PID cgroup hard limits), streamed real-time telemetry over thread-safe queues via SSE, and built an AST-based line-level parser (cutting context/generation bloat by ~80%). Achieved a 100% resolution rate (5/5) on a custom Micro-SWE-bench harness with an average time-to-resolution of ~205 seconds.
• SentinelPrime (https://github.com/sriramvarun0636/SentinelPrime): Multi-threaded, regime-aware options trading system for live WebSocket market data. Releases the CPython GIL during numerical computations using Numba JIT compilation (nogil=True) and an Actor Model architecture over daemon threads to isolate DB I/O and API calls. Built thread-safe O(1) queues and fixed-size circular memory buffers to eliminate allocation overhead under 24/7 continuous operation.
• HydraPrime (https://github.com/sriramvarun0636/HydraPrime): Systematic XAUUSD strategy in MQL5 (C++ derivative), developed and iterated solo over two years — OTE/Fair-Value-Gap structural entries with ATR-adaptive sizing and multi-layered drawdown circuit breakers. Backtested across 96M+ real ticks over a single two-year window (2024–2026) that included a strong gold bull run: 1.37 profit factor, 13.8% max drawdown, 252% net return. Not yet forward-tested live, so I hold that return number loosely until it survives a different regime.
What I'm looking for:
Backend/infra/agent-systems roles at early-stage teams, pre-seed to Series A — founding engineer or engineer #2–5, wherever you're at. Standard interview loops work fine too, not just trial sprints.
I am a software developer and researcher with half a decade of experience and a Master's degree in mathematics. I have ample experience with Golang in a professional context often on backend services like REST APIs and programs interacting with databases and message queues, am fairly proficient with a variety of other languages and technologies, and am comfortable working on a variety of domains, from accounting/financial management/CRM software, to IaaS products, to scientific and mathematical software and language apps. I enjoy learning, and am always open to learning new things, especially if they happen to ignite my curiosity.
I like free or open-source software, systems programming, web services and the infrastructure required to run them at scale and would love an opportunity to continue to contribute to and learn about them. I enjoy mathematics and quantitative research like biology, engineering and physics. I enjoy writing, and in particular writing documentation for software, educational content, and research.
I am happiest working with people who are open-minded, conscientious and kind, and I try very hard to always embody those qualities.
I am open to both full-time employment and contract work.
I am a French citizen and can work freely anywhere within the EU.
Compensation for in person work is location-dependent, and more expensive than full-remote work, due to the extra work involved (physical, moving things around in meatspace work, not just pushing bits around cyberspace). That said, I do really enjoy being in nice offices and hanging out with the team while working, and also really enjoy occasional "team in-person meetups" even when working in a full-remote context.
- Desktop, embedded, web, backend, some mobile (mostly iOS)
- Burn, GGML, NumPy, some JAX, some Mojo, some MLX
Rust is definitely my favorite and TypeScript is up there as well.
At my last company, I worked on developer experience and performance optimization. The one before that on user experience and polish. I work best on storms of small things, tend to get wrapped up on big projects.
I am fully self-taught, have been doing this for over 10 years & have a beefy personal machine (macOS or Windows). I have about 3 years of professional experience. I am available to interview immediately and can start immediately. Contact me with anything.

Senior software engineer. Extensive front end and back end experience. I've spent most of the past four years building AI agents and related system.
I built an open-source, plugin-based agent framework. It supports tools, delegated jobs, knowledge bases, browser and computer control, database access, custom UIs, and image/video workflows.
Lately I've been working on a low-latency, self-hosted voice agent system that uses direct SIP, streaming STT and TTS, Qwen 27B, and vLLM.
I'm also building a browser-based 3D AI character project as a side project. It runs small models such as Gemma 4 and MiniCPM 5 locally through WebGPU. Other recent work include employment verification, medical document processing with complex RAG, browser automation,interactive avatars, and data analysis agent workflows.
Most of my work crosses several layers of the stack. I'm comfortable with frontend and backend web development in Python and Node.js, agent design, model serving, infrastructure deployment. I especially like greenfield projects, though I don't need everything to start from scratch.
Recent: Owned Rust incentives/rewards services end to end (lifecycle state machines over 200K+ users, idempotent event-driven payment engine, Kafka). Built a review-gated AI delivery harness that shipped 10+ production features (four in one week in the same codebase).

Full-stack engineer, B.S. Math-CS from UC San Diego
I build and run GratMap (https://gratmap.com) a live production web app I designed, built, secured, deployed, and operate solo. React + Mapbox front end, Express/Node + MariaDB back end, on a Linux server I administer myself. Two parts I'd point at: a venue-scoring pipeline that shrinks each venue's median toward the global median in proportion to how much data it has, so a two-report venue can't outrank a two-hundred-report one; and a pre-launch security audit checking for breached-password screening via HIBP k-anonymity, rate limiting, JWT in httpOnly/sameSite cookies, ORM parameterization.
Before that I was the founding engineer at Citmit, a construction-permitting SaaS startup. I joined when they had a product plan and no engineers, built the initial codebase and infrastructure from scratch, and led a team of four through alpha. I implemented Stripe billing, an S3 document pipeline, and the application-side integration for their LLM feature.
I work in Claude Code every day and can explain and debug what comes out of it without it.

I was laid off by Cisco Meraki last summer, where I spent four years as a technical lead for the cloud side of the wireless products. I have experience in both web development and cloud infrastructure roles.
I have worked for years in open source software development. I created and ran two notable open source projects: Lita, a ChatOps framework for Ruby (https://github.com/litaio/lita) which is used by many companies for automating internal operations and workflows, and Ruma, an implementation of the Matrix protocol in Rust (https://ruma.dev/) which went on to become the basis for the official Rust SDK for Matrix.
My ideal role would be building software targeting other developers, either as a member of a developer tools team, or for a company whose products are made for developers. I'm also drawn to companies building "neutral" utilities whose value is fairly self-evident: Things like PagerDuty and Stripe which are generally useful and provide the infrastructure needed for other things to work.
I would love to use Rust professionally, but I'm fine with other languages, too. I'd also be very happy to work on a product with an amount of open source code, given my background working on OSS projects.

Product Designer with 11+ years of experience in design, research, and some front-end. I've worked on design systems, AI-powered dashboards, fintech, fleet mobility platforms, B2B and B2B2C SaaS, and standards development. Most recently I was working on skills to facilitate prototyping spec-accurate designs and flows for ecommerce, as well as another skill to enable client-facing teams to create full prototypes for pre-sales demons. I've worked in both startups and large corporations, and I'm interested in opportunities where I can learn and build on top of designing for complex systems.

I build and run PersonaChat (personachat.chat), an AI character chat platform on Next.js and Supabase — live since 2025, built and operated solo.
Production LLM work rather than demos: streaming chat over the Vercel AI SDK; a long-term memory layer with append-only writes and invalidate/supersede semantics, idempotency keyed on source turn ID so a dropped stream never duplicates a turn; a relationship engine holding state across sessions that feeds back into generation; and the same character system running through a Discord surface, which forced the state logic out of the components into a shared layer.
I also instrument and read my own funnel in Postgres rather than guessing, and I run Claude Code daily against structured specifications rather than prompts — agents write most of the code, the spec and the review are the job.

SEEKING CONTRACT WORK - Forward deployed engineer, remote, email in profile. Location: West Coast, remote only.
I'm a forward-deployed engineer. My background is 15+ years of data science, but I focus on solving problems. I work in messy, ambiguous, regulated environments. Often at a client's site, inside their systems and their data. I excavate unmapped data, learn how the team works, and ship tools that stay in production.
Deployed and still running today: Legal clause extraction and validation; site corrosion detection and management; routing and predictive-maintenance systems that stayed in service.
I compress engineering, data, and modeling into one function, owned end to end. I show up, figure out what needs to be built, and make it work.
Tooling: ML/AI, LLMs, and the engineering around them: evals, determinism, observability, guardrails. The tech is just a tool, The hard part is knowing what to build.
If you have a messy, ambiguous problem that needs someone who can embed and ship, my email is in my profile.
EDIT: Corrosion detection so people don't think I detect rust code. (Nothing wrong with that though)

AI-assisted Full-Stack TypeScript developer looking for a remote frontend/full-stack/implementation role.
I’m strongest at taking a loosely defined product task and pushing it all the way to a working result: codebase research, implementation, debugging, testing, deployment, and post-deploy fixes.
My main project is a production CRM built with Next.js/TypeScript/Node: authentication, per-user data isolation, projects and financial tracking, analytics, multi-currency support, an LLM assistant with persistent conversations, CI, automated tests, backups, and deployment on a Linux VPS.
I’ve also built automation/data-processing tooling for 20k+ structured records, worked with REST integrations and Bitrix24 data, and debugged real deployment issues across APIs, SMTP, builds, environment configuration, Nginx and PM2.
I use coding agents heavily, but not as a black box: I inspect the existing codebase, define the scope, review diffs, run type checks/tests/builds, reproduce bugs and verify the result manually before calling a task done.
I’m not looking for a role where “junior” means only converting Figma into components. I’d like to work close to the product and own real problems across frontend, backend, integrations, automation and internal tooling.

Applied physicist and engineer, 15+ years. Put me on a messy, physical, high-consequence problem that crosses disciplines and has to ship — not demo.
Recent: 6 years at Agilent building production ML over instrument telemetry — fleet-wide failure prediction, and a RAG/LLM system for 300+ field engineers taken from prototype to production (including the confidence logic for when it answers vs. hands off to a human). Cut data-prep time 8x.
Before that I built scientific instruments from scratch — a fiber-based STED nanoscope and an OCT microscope — so I know data from the sensor up, not just after it lands in a warehouse. Earlier: DoD hardware reliability (former TS/SCI), precision timing, published detector-physics work.
Strongest where software meets the physical world: instrumentation, sensor data, ML that has to be right because being wrong has consequences. I own problems end to end, and I'll tell you when the result isn't trustworthy yet.

22, self-taught. Won a $100K Meta Llama Impact Grant for Bluai and presented it at LlamaCon on 2025
Bluai (https://play.google.com/store/apps/details?id=com.bluai.app&...) is a hurricane early-warning app live on Google Play in Mexico, built offline-first because during a hurricane the network is the first thing to go. An online RAG pipeline and an on-device Llama 3.2 (ExecuTorch, NPU-accelerated) sit behind one interface, picking 1B or 3B based on device RAM, so the UI never knows which brain answered. When everything is down it falls back to Bluetooth/Wi-Fi mesh chat over a multi-hop wire protocol.

System design is my native mode of thinking. I'm a great person to have around if you're building something where the rules and patterns aren't established and the problems need to be worked through from scratch, whether that's interaction design, architecture or algorithms. I also know React and web technologies pretty well.
I'd been coding for maybe 15yrs before LLMs and agents hit, but I've deeply re-worked how I approach it over the past couple of years. I'm still learning and adapting as the tech develops like everyone else, but working with LLMs and agents is second nature at this point. I've tested the limits, and I've been through the pitfalls.
I have a portfolio here: https://symbolflux.com --though unfortunately it doesn't have much of anything from my AI-related work yet. Here's a writeup discussing the design of an LLM/agent system I was developing earlier in the year though: https://symbolflux.com/working-group-foundations.html

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot instances for satellite image processing at Urthecast.

Before this, my background was postdoctoral biophysics and ML research (GROMACS, SLURM, ML-assisted free-energy prediction) plus contract cloud engineering at a startup.
I'm a strong fit for platform, infrastructure, SRE, DevOps, or computational research roles. I do my best work in small, collaborative teams, and I'm comfortable wearing many hats.
Experienced with working in distributed teams.
Looking for full-time, part-time or contract work.

Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.
I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.
Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu
Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.

Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice.
Due to high interest in my work with recursive self-improving coding agents, I've shared an example repo at https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows.
I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering and complex frontend architecture.
Notable projects include custom legal document management dashboards and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across fintech, streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments.

A passionate problem solver with over fifteen years of experience, currently a founding engineer at a self-funded startup building a design and prototyping tool. Before that, I worked mainly as a full-stack engineer at SaaS companies.
Problem solving for me does not stop at the product/code, I'm always finding ways to improve the development process or help colleagues get unstuck by mentoring and coaching. Also I'm not afraid to learn a new programming language/framework or to dive into the infrastructure.
Are you looking for a seasoned, product-oriented software engineer who cares about user experience and can drive a feature from idea to implementation?

I build LLM systems that run in production. The clearest example is live: pick a sector at https://demo.consentleads.uk and message it the way a customer would. Nothing is scripted. It runs on a free-tier ARM box behind a Cloudflare tunnel, is multi-tenant and has users, and nine scheduled jobs keep it going unattended.
If opt-out detection misses a phrase, the system keeps emailing someone who asked it to stop, and nothing crashes or alerts. So the suppression gate fails closed, and the eval fixtures cover that path and reply triage.
I also wrote claimcheck (MIT, https://github.com/visione4906/ctaio-claimcheck): give it a document and a codebase and a second agent has to prove every claim against the source with file and line citations, or the build fails. I built it after an outside review of my own writing turned up claims the code did not support.

I started as a fullstack JS engineer and grew into product development at my last company. I owned the ingestion layer - collecting 100k relevant messages/month from 4 platforms through a dirt-cheap serverless back-end on Cloudflare Workers.
We worked with LLMs deeply, especially in code generation. I was part of a small team developing SpecGEM, a fine-tuned model that generates Cloudflare Workers code from JSDoc comments and is designed to outperform mainstream LLMs at this narrow task.
I just released an open-source self-hosted LLM assistant on Cloudflare Workers that predictably compounds context across conversations. https://github.com/kol3x/pawmc

Full-stack engineer, 8 years, front-end deep, CET. I take over live systems and restructure them without stopping the roadmap. At Jebbit (L'Oreal, AutoZone, NFL, ~1M sessions/hour) I led a four-month refactor that replaced a per-row style override system with one merged JSON schema, backwards compatible with both running in parallel. Currently on a consumer AI product where I own features end to end and took page load from 3s to 1.5s and a deep component from ~300 re-renders to ~10.
AI-native: I don't hand-write much anymore, I spec work and drive agents against it, and spend my time on judgment and review. Claude Code and Cursor daily.

Final-year CS student and backend developer with a systems-programming leaning. I like working with backend systems, More than that I am eager to learn from anyone. Apart from my coursework I have worked on - crawlers, TUIs and rate-limited APIs.
Open source / recent work:
Contributing to the Linux kernel - submitted patches to drivers/staging/rtl8723bs/ (checkpatch cleanups), currently working through review feedback with the maintainers. Built web_weaver, an async Rust web crawler from scratch: tokio-based concurrency, per-domain rate limiting, robots.txt compliance, SQLite + FTS5 storage, crawl resumption via a persistent queue. First of a planned three-part research/search tool. Comfortable across the backend stack: Go and Rust for services, Postgres/Mongo for storage, some exposure to Elixir and Zig.
Based in India (IST), but can shift my hours to get a solid 3-4hr overlap with EU or US mornings - happy to discuss specifics.
Looking for a remote backend or systems-adjacent role at an established company or a startup with real funding/traction/team - not a pre-idea-stage solo founder project or a "let's see if this works" 3-month gig. Open to relocating for the right role if the company is based in India. Happy to do a proper interview process; if you're reaching out, a link to your company/product and team size is appreciated so we can both save time.

I’ve spent about half my time in first/founding engineer roles at startups, and half working directly for clients, agencies, and institutions on a wide variety of products. Folks enjoy my enthusiasm for their ideas and my ability to meet them where they are technically, always providing that extra context that builds trust and understanding.
I’m comfortable owning concerns end-to-end, from initial scoping and architectural tradeoffs through deployment of functional prototypes and user testing. I enjoy iterating and scaling systems from there, while building teams to maintain and build upon them.
Expertise in database design, media rendering systems, engagement platforms, high-volume event ingestion, ML pipelines, and getting it all working in AWS. Top priorities are data integrity, security, and privacy.
Lean on me for:
- Technical scoping and planning for a new product or platform before committing resources
- Architectural review and data modeling to see how a system should flow and which tradeoffs matter
- Greenfield builds where you need someone to plan and ship v1 without much hand-holding
- Forward-deployed engineering, working directly with potential customers to help guide the product
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.

Email: savenko.sy@gmail.com
Senior Ruby/Rails engineer, 11+ years. My specialty is data-heavy Rails: making it fast, and making it correct.
- Partitioned PostgreSQL at scale — ~330M rows / ~220GB in production, entity resolution and duplicate-merging across 100M+ row tables - Query performance — 5–40x speedups by restructuring schemas and moving hot paths off Postgres onto OpenSearch - Billing engines — rebuilt one for ~10x faster calculation and ~50% smaller database (ActiveRecord→ROM), another for a 5x speedup on the bill pipeline - Recently — pgvector/RAG inside Postgres, LLM integration in Rails (RubyLLM, MCP tooling)
Likely a good fit if you have a Rails app outgrowing its database, a billing or usage-metering system that's slow or subtly wrong, or you want RAG without bolting on a separate vector DB.
Open to full-time or contract. 4+ hours of daily overlap with US East now; the Lisbon move in November adds 2 more. I invoice through a registered sole proprietorship with a W-8BEN on file — no US withholding under the treaty, nothing for a finance team to set up.

I build the tool layer that agents call, and I've had one in production long enough to know where it breaks.
At Chronicle I built our hosted MCP server end to end — eight tools that Claude and ChatGPT authenticate into over WorkOS OAuth with JWT and async polling, running on ECS. Also our first public REST API and the developer docs, a workspace-scoped API key system for tenant isolation, and an npm node that had to pass n8n's strict-mode security review before listing. On the interface side, an AI-generation UX with streaming tool-call visualisation, cancel/abort mid-flight, and live document editing over CRDTs.
What I've learned is that agent failures are boring and specific rather than clever. I lost four days to what looked like an auth error and turned out to be a tool declared without an input schema, silently changing the signature the SDK used to call my handler. Four theories before I read the error string properly. I write the theory down before chasing it now.
I also shipped Recall (https://recallapp.online) solo in about two weeks — notes into flashcards over MCP, with FSRS scheduling. Design, backend, payments and launch were mine. #22 on Product Hunt. Before Chronicle I owned a Shopify-to-custom-platform migration end to end, including ingest pipelines from three sources into Postgres.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Open to full time or contract.
I look forward to talking with you!

About: I am a Generative AI Engineer who also happens to be pretty hands-on across the full stack development. Most of my recent work has been building RAG pipelines, AI agents, and natural language search — using LangChain, LangGraph, and vector databases like Pinecone and ChromaDB — with OpenAI, Anthropic, and Gemini APIs under the hood. I care deeply about shipping GenAI features that hold up beyond the demo stage.
Beyond GenAI, I am working on the full stack — React/TypeScript on the frontend, Node.js or ASP.NET Core APIs on the backend, and AWS/Azure for infra. I like owning things end-to-end and building software that's simple and reliable.

Software Engineer with 3+ years of experience building frontend applications, backend services, automated testing pipelines, and AI-powered developer tools. At my current company, I've improved Angular applications, built Spring Boot microservices with 100% unit test coverage, automated Playwright regression testing (reducing execution time from 2 hours to 30 minutes), and developed an AI-powered MCP server that generates Playwright tests from natural language, reducing test authoring from 45 minutes to under 2 minutes per spec. I enjoy building products end-to-end rather than working on isolated tickets. Recently I've been focused on AI developer tooling, RAG pipelines, MCP servers, and LLM-powered automation alongside traditional backend development. Some highlights:
• Spring Boot microservices and REST APIs • Angular, React, Next.js, Node.js • AI Agents, MCP, RAG pipelines, vector databases • Playwright automation and developer productivity tools • AWS, CI/CD, SQL
I'm looking for a remote backend, full-stack, or AI engineering role where I can own features, work closely with a product team, and build software that ships to users. Startups and product companies are especially interesting.
If you're looking for an engineer who enjoys solving problems, automating repetitive work, and shipping production-ready software, I'd love to talk.

Trying something different again here, sorry.
I'm looking for monthly/yearly "no-strings" sponsors, not employment, if any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent.

I build data pipelines that know when they're lying to you.
GAScout (https://gascout.pages.dev) — Georgia public-records pipeline. Four counties live, each a different ingestion problem resolved into one schema: a 9,915-page fixed-width mainframe PDF (409,142 records, zero dropped rows), a weekly XLSX roll, monthly text PDFs, and scanned sheriff's levy documents via OCR. Adding a county is a config file, not code. The other 155 are labeled planned rather than filled with invented numbers.
FindStorage (https://findstorage.pages.dev) — national self-storage pricing tracker. 4,639 locations, 245,000+ price changes logged, running unattended on a daily schedule. Aborts rather than publishing when the store count moves more than it should, because the failure that costs you isn't a crash — it's a scraper quietly returning less after a site changes and nobody noticing for three weeks.
Also built a WiFi CSI device-fingerprinting array on ESP32 — custom ESP-IDF firmware and a Python DSP pipeline, running as my apartment's security system. Cross-manufacturer separation holds at 11-15 sigma; same-model discrimination tops out near 77% and true clock twins are the open problem.
Before this I ran a 500-acre motocross park in Northern California: acquired dormant land, re-entitled it, directed a 120-person race-day crew, ran the medical plan through a mid-event helicopter evacuation, and sold my stake.
Self-taught, ~18 months in. Interested in data engineering, pipeline work, and anything where messy real-world sources have to become trustworthy structured data.

I'm Jeff, an experienced developer with pretty broad experience. I've done things like robotics control software and video processing software, all the way up to scalable enterprise applications and big-data ETL automation. In my free time I write games, language runtimes, and hack the NetBSD kernel for fun. I freakin' love to program, and I love crafting straightforward, effective solutions that serve the user.

Ava, a real-time captioning platform for one-on-one and group conversations, online and in person. 11+ years, zero to product. I co-founded it and was CTO, but the backend was mine throughout, first building it and later as Backend Lead. What that covered: the live captioning pipeline, where latency, accuracy, and reliability all had to hold at once. Drove the backend from a monolith into a monolith plus microservices plus serverless, over an event-driven layer, to keep service stable. An observability stack with Prometheus and Grafana, built from scratch. A datastore migration across 100K+ accounts with no downtime, running both databases live instead of taking a batch window. The subscription and enterprise licensing backend behind customers like Disney and Nike. Penetration test remediation three years running across four teams. On call for all of it. None of this was a fresh start. Everything was already running, with real users on it, and it had to keep running while I changed it.
How I work: most of what I've built started as a vague idea, and my job was making it specific enough for other teams to build against. I own my scope end to end, and once people start building, the spec always changes. That back-and-forth is where the design actually gets figured out.
Two projects I'm working on now:
Clearway: audits websites for accessibility and drafts the compliance report a specialist would write by hand. False alarms 43% to 23%, real issues caught 74% to 83%. My first AI reviewer scored well on my own gold set and near zero on the external W3C one, because it shared a rubric with the drafter. A second reviewer reading independently now catches 53% of those errors. Small-sample measurements, not proof.
VOX Personalis: fine-tuned Whisper with LoRA on my own Deaf-accented speech, because no off-the-shelf ASR handles it. WER 238.69% to 34.05%, now with sub-second streaming output. Next is sub-20% and on-device.
Communication style: I'm Deaf and work best with text-first collaboration, clear written specs, async updates, and captions/transcripts for meetings. This is how I've worked for 11 years, including with enterprise customers.
Looking for: Senior Backend IC, MTS, or Founding Engineer scoped to backend and agent infrastructure. Seed to Series B, applied AI, SF onsite or hybrid, full-time. Going deeper, not wider. I want to put a deep backend foundation to work on the part that’s hard: making a service reliable on top of an LLM that isn’t deterministic.

I build the systems plumbing, concurrent pipelines, and secure runtime isolation that AI coding-agent startups are racing to ship. Happy to prove it directly on your codebase first — I'll take on a 2-3 week paid trial sprint on a real backend bottleneck before any longer-term conversation.
Computer Science Engineer (MNNIT Allahabad). Formerly Software Engineering Intern @ DeeveloX (preprocessed 5GB+ vector search datasets with Gemini APIs).
Recent High-Agency Projects:
• AutoPatch-AI (https://github.com/sriramvarun0636/AutoPatch-AI): Autonomous, self-healing code remediation agent built on a LangGraph state machine. Engineered a zero-trust Docker execution layer (network_disabled=True, 256 MB RAM / 128 PID cgroup hard limits), streamed real-time telemetry over thread-safe queues via SSE, and built an AST-based line-level parser (cutting context/generation bloat by ~80%). Achieved a 100% resolution rate (5/5) on a custom Micro-SWE-bench harness with an average time-to-resolution of ~205 seconds.
• SentinelPrime (https://github.com/sriramvarun0636/SentinelPrime): Multi-threaded, regime-aware options trading system for live WebSocket market data. Releases the CPython GIL during numerical computations using Numba JIT compilation (nogil=True) and an Actor Model architecture over daemon threads to isolate DB I/O and API calls. Built thread-safe O(1) queues and fixed-size circular memory buffers to eliminate allocation overhead under 24/7 continuous operation.
• HydraPrime (https://github.com/sriramvarun0636/HydraPrime): Systematic XAUUSD strategy in MQL5 (C++ derivative), developed and iterated solo over two years — OTE/Fair-Value-Gap structural entries with ATR-adaptive sizing and multi-layered drawdown circuit breakers. Backtested across 96M+ real ticks over a single two-year window (2024–2026) that included a strong gold bull run: 1.37 profit factor, 13.8% max drawdown, 252% net return. Not yet forward-tested live, so I hold that return number loosely until it survives a different regime.
What I'm looking for: Backend/infra/agent-systems roles at early-stage teams, pre-seed to Series A — founding engineer or engineer #2–5, wherever you're at. Standard interview loops work fine too, not just trial sprints.

I am a software developer and researcher with half a decade of experience and a Master's degree in mathematics. I have ample experience with Golang in a professional context often on backend services like REST APIs and programs interacting with databases and message queues, am fairly proficient with a variety of other languages and technologies, and am comfortable working on a variety of domains, from accounting/financial management/CRM software, to IaaS products, to scientific and mathematical software and language apps. I enjoy learning, and am always open to learning new things, especially if they happen to ignite my curiosity.
I like free or open-source software, systems programming, web services and the infrastructure required to run them at scale and would love an opportunity to continue to contribute to and learn about them. I enjoy mathematics and quantitative research like biology, engineering and physics. I enjoy writing, and in particular writing documentation for software, educational content, and research.
I am happiest working with people who are open-minded, conscientious and kind, and I try very hard to always embody those qualities.
I am open to both full-time employment and contract work. I am a French citizen and can work freely anywhere within the EU.
Compensation for in person work is location-dependent, and more expensive than full-remote work, due to the extra work involved (physical, moving things around in meatspace work, not just pushing bits around cyberspace). That said, I do really enjoy being in nice offices and hanging out with the team while working, and also really enjoy occasional "team in-person meetups" even when working in a full-remote context.

Technologies: I am full-stack and have been almost everywhere in the consumer market:
- Rust, TypeScript/JavaScript/Node.js/Bun/Deno, Swift/Obj-C, C/C++, Python, Go, C#
- Windows, Linux desktop/server, macOS/iOS, some BSD (mostly from macOS)
- Tokio/Rayon, React.js/Svelte/Angular, SwiftUI/some AppKit, wxWidgets, Asyncio/Twisted
- Desktop, embedded, web, backend, some mobile (mostly iOS)
- Burn, GGML, NumPy, some JAX, some Mojo, some MLX
Rust is definitely my favorite and TypeScript is up there as well.
At my last company, I worked on developer experience and performance optimization. The one before that on user experience and polish. I work best on storms of small things, tend to get wrapped up on big projects.
I am fully self-taught, have been doing this for over 10 years & have a beefy personal machine (macOS or Windows). I have about 3 years of professional experience. I am available to interview immediately and can start immediately. Contact me with anything.
