If you can dream it, you can do it.
Walt Disney

I build and teach the stuff that runs things: AI systems and LLM agents, software architecture, Linux, DevOps and observability. Day to day that means wiring LLMs into real products, running agentic pipelines in production, designing APIs and keeping the servers underneath them boring and reliable. I work for business and government clients and have been an Open Source contributor and user for a long time.

I prefer presenting ideas over presenting myself. But it seems that no freelancer or trainer exists without an "About" page. So rather than listing all things I've achieved and failed at, I am just going to share my profile and spare you the marketing speech, everything else can or can not be found on Google.

Trainer Profile

More than 3000 training and consulting days since 2010 for countless companies in Germany and Europe. Speaker at national and international conferences. These days most of it is about AI: helping developers and teams actually use LLMs and agents, not just talk about them.
