Welcome

I'm a proud father and an ultrarunner, with an extensive background in catering & events. I'm enthusiastic about programming, AI, Linux, investing and art.

This site is hosted and developed by me.

Currently I'm working full time as a full stack developer and coach at Sitowise and writing a thesis on privacy first tech stack tuned LLMs.
