Mariusz Koziel - Ruby community in Poland, how to become CTO and CEO

Mariusz is an old friend of ours. Over the last few years, we've chilled 🍻 at many events around 🇪🇺
He works at an iconic ruby consulting shop in Warsaw, Poland (Visuality), where he was recently promoted from CTO to CEO.
Mariusz gives back to the 💎 community by organizing local meetups (Warsaw, Lodz) and organizing conferences.
In July 2023, he organized the first "Warsaw Community Conference".
Just 6 months later, he is organizing the second edition of Warsaw Community Conference on 02 Feb 2024.
It can be a great opportunity to visit Warsaw and meet old friends!
