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, mostly by AI engineering nowdays.

Currently working as a full stack developer and coach at Sitowise and finishing a master's degree in AI & Data Engineering.
