Beata Nowakowska 
Beata is a developer, Scrum Master, Agile and business coach. She started as a developer and quickly became the refactoring-guy-on-duty for the team and the teacher of all the quality stuff. At some point she realized that there is something even more important than clean code. Something that creates environment where writing clean code is easy and natural. She got interested in Agile and Scrum and soon started spreading that knowledge together with clean code.
