Behind the projects

About me

An engineer by profession. Curious by nature.

I like cars, technology and old gadgets. I also enjoy tinkering with things that probably worked perfectly well before I got involved.

From software and AI to Linux and retro hardware, there’s always an excuse to learn something new or make life a little more complicated.

This is where I share my projects, discoveries and experiments.

Sometimes, I just want to see if it can be done.
