Welcome

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

This site is hosted and developed by me. The site runs on Linux, Apache, PostgreSQL and Django.

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