I build AI agents, LLM integrations and RAG systems in Python, Django and Node.js, plus the backends they run on. 5+ years shipping web apps, APIs and microservices for startups and growing businesses. What I build - AI agents with tool calling on the OpenAI API: bounded runs, retries, timeouts, cost limits and logs you can trace - RAG assistants that answer from your documents with citations, and say "I don't know" when the source doesn't cover it - Voice agents with streaming responses and fallbacks - AI features inside your existing product: chat panels, document assistants, and actions that wait for the user to confirm - Backends and APIs in Django, DRF and Node.js/Express, with PostgreSQL, Redis and Docker - Real-time systems with WebSockets, Elixir/Phoenix and LiveKit Recent work - AI-agent workflow (Upwork client, 2026): the tool-calling layer on the OpenAI API, with retries, timeouts, cost handling and structured logging. 5.0 review. - Matrix Bingo: backend for a live multiplayer bingo platform (auth, game logic, WebSocket flows, LiveKit). Ongoing contract since March 2025, 270+ hours. - Long-term website upgrade (2025 to 2026): "dependable and invaluable... genuinely life-saving at critical moments." - Public Library Management System: as part of a team, built Django and Express microservices behind an API gateway, used by 60+ district branches. - Independent projects on GitHub: hybrid RAG with reranking and citations, an eval set with a CI regression gate, and a streaming voice agent. How I work - For AI features, I plan for what demos skip: permissions, cost, wrong answers, failures and logging. - Clear, regular updates. One client wrote: "updating his clients the best I've ever had." - Based in Finland (EET). I usually reply within a few hours. Tools: Python, Django, DRF, Node.js, Express, React, PHP/Laravel, Elixir/Phoenix, PostgreSQL, Redis, Docker, OpenAI API, LiveKit. If you need a dependable developer who can build across the stack, integrate AI where it actually adds value, and deliver clean software without unnecessary complexity, I’d be happy to help. Send me your current stack and what you want the AI to do. I'll reply with a short plan and the questions I need answered first.
