Mateusz Jurzyna

Product-minded engineer with 12+ years building end-to-end digital products — from rapidly prototyping ideas to shipping them at production quality. I work at the intersection of engineering, product discovery, and delivery. My sweet spot: frontend-senior, extending into backend and AI on full-stack product work. — Currently founding engineer on Restora (via Nexus Collective) — an AI-powered clinical documentation platform for psychologists. I own the product cycle end-to-end: UX research with practising therapists, UI design, frontend (Next.js, React Native), and hands-on Node.js/PostgreSQL + LLM integration for structured text generation (session summaries, clinical notes). Also building TFC — a digital VAT refund platform with Polish government system integration (PŁESK, OCR, QR for customs). — What I bring: - Zero-to-one product building — from user interviews to production - Senior frontend (TypeScript, React, Next.js, React Native, Flutter) - Rapid prototyping and shipping to production at quality - AI-assisted development (LLM integration, RAG, MCP, structured outputs) - UX research, design systems, and product thinking — Open to remote Principal / Senior Product Engineer roles across Europe. Let's talk if you're building something at the intersection of product, AI, and frontend.
