Welcome!


I'm a Linux-oriented developer. I publish articles and tutorials on stuff that I experiment on.

I have an extensive background in catering & events, and 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 develop at Sitowise.
