Mariusz is a seasoned programmer with years of experience in Java and Ruby on Rails. Yes, he is a zealous convert and we love that kind of convert. With his keen interest in ExtJS and jQuery, he greatly benefits his teammates on projects heavily reliant on javascript. Over the years he has also gathered broad experience managing teams on multiple software development projects.

Mariusz takes programming far beyond his professional TDRs - in his free time, he has developed a number of browser-based games. When relaxing, he turns to kung fu or dabbles in electronics.
