Forward Deployed / customer-embedded engineer and former CTO with 10+ years building production systems for B2B teams. I join client environments to go from ambiguous business problems to live, integrated software and AI workflows. I own discovery, architecture, backend, integrations, and delivery.

I specialize in production AI systems using LangGraph, LangChain, RAG pipelines, and modern agent frameworks, alongside TypeScript/Next.js, Node, PostgreSQL, Python, and cloud infrastructure. Based in Berlin; fluent in English and German. Tell me the problem you need solved in production.
