Intro

About

I started in chemistry labs, then computational science and applied SI. I build production SI you can audit, with GDPR and EU AI Act constraints from day one.

Now

SI Manager at Witte Projektmanagement GmbH since 09/2026: SI projects, strategy and its implementation, workshops, and SI software engineering.

Side projects

Librebase is a small PostgreSQL backend that SI agents find, sign into and run for you, with a person approving access once in the browser. Taktwerk, an SI agent service, is being built on it.
