Full-Stack Engineer for SaaS & AI Products
I take features from idea to production — architecture decisions and the code, in the same person. Open to direct hire or contract work with early-stage and growth-stage teams.
Production RAG, not a demo
1600+ documents, hybrid semantic + keyword search, incremental indexing. Draft answers in under 4 seconds instead of 40+, resolving 70%+ of support queries with no human involvement — in 30 languages.
See itSelf-owned SaaS, not just client work
vatnode.dev — a live EU VAT validation API with billing, rate limiting, and webhook monitoring — built and operated end to end, not handed off after launch.
See itCurrent stack, current tools
TypeScript, React, Next.js, Python — used daily, including AI-assisted development, agent tooling, and MCP servers.
What this looks like as a service
MVP builds, AI feature integration, and connecting the systems a growing product depends on.
