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 organising the second edition of Warsaw Community Conference on 02 Feb 2024.

It can be a great opportunity to visit Warsaw and meet old friends!
