Senior full-stack + AI engineer (10+ yrs). I build AI products end-to-end and the stack around them — shipped a SQL AI copilot at CData (Gartner D&A 2025) and an eIDAS/EUDIW identity wallet. Open to contract (preferred) or a senior IC role.
Senior full-stack & AI engineer (10+ yrs) — EU + US clients.

Remote: Yes (only) — EU and US-overlap, async-comfortable, happy to take occasional late sync calls
Willing to relocate: No

AI / LLMs — Anthropic + OpenAI SDKs, RAG, structured outputs, fine-tuning (Qwen3 on MLX), multi-model orchestration, NL→SQL
Backend — .NET / C#, Node.js, PostgreSQL, Hangfire, Stripe
Frontend — TypeScript, Angular, React, React Native
Identity — OAuth 2.0 / OIDC, OID4VP / OID4VCI (eIDAS 2)

10+ years shipping production software:
- CData Virtuality (AI research team) — solo-shipped a Cursor-style SQL AI copilot inside the platform; Q3 2025 release, demoed at Gartner D&A Summit 2025
- VMware Workspace ONE — identity & MDM
- TestGorilla — micro-frontend platform
- Octopus Energy Germany — 40K-user billing migration
- Co-founder / engineering lead, Insight Draft (AI meeting SaaS, app.insightdraft.com)
Two technical case studies of recent end-to-end work (source for both is on my GitHub):
— Insight Draft: Chrome extension records Meet / Teams / Zoom without bots joining the call (tabCapture + desktopCapture). 6 LLM call types per meeting via Task.WhenAll, OpenAI Responses API with strict structured outputs, statistical-voting speaker mapping, custom Hangfire fan-out/fan-in primitive on top of Postgres atomic UPDATE...RETURNING. https://petropavlov.dev/case-studies/insight-draft
— Gramota (EU Digital Identity Wallet SDK, gramota.eu): 15 published npm packages with Sigstore provenance, ~580 mock + 31 live tests against the EU Commission reference infrastructure. 12-check verifier pipeline, per-org x509 + signed JAR, DCQL matcher, OID4VCI Draft 13/14/15 normalization. https://petropavlov.dev/case-studies/gramota
Strongest fit is AI product work where someone has to ship from prompt through to production billing, identity, and integrations — but happy to chat about anything in or adjacent to this stack.
Remote: Yes (remote-only)
Willing to relocate: No
Technologies: TypeScript/React/Next.js, Angular, .NET, Python, Postgres · AI: RAG, LLM fine-tuning, NL→SQL, agents
