About Mariusz Koziel

I’m a software engineer who became a team lead, engineering manager, CTO and CEO at the end :) On top of that I'm a founder of 'Ruby Europe', 'PLRUG Warsaw Ruby Meetups' and 'Ruby Warsaw Community Conference'! I focus on relationships with my team-mates as I believe that constant feedback and growth are two essential factors to have a great working environment. I also enjoy being part of our clients’ businesses - with time i realized I have growing knowledge that can help them grow - not only in technical terms.
