AI Engineer & Senior Fullstack Developer · Hamburg, Germany
Fullstack developer based in Hamburg with more than ten years of experience. My core is TypeScript with Angular and Node.js; since 2025 that includes Python for machine learning, and since 2026 React/Next.js, Java and Spring Boot. I design, build and operate LLM-powered products – with approvals, cost limits and data protection designed in from day one.
