I'm a frontend and full-stack engineer in Berlin. TypeScript and React since 2015, Next.js since 2019, and for the last two years an open-source LLM engineering platform at @Agenta-AI.
I keep large codebases easy to work in, refactors included, and I build LLM tooling and the workflows around it.
Agenta is where most of my recent commits are. Prompt playground, prompt management, evaluations and observability, and since mid-2026 an agent builder.
