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!
