SPIL GAMES
Rafał is one of the best developers I have had the pleasure working with. First one on one when working on A10.com and later on when he acted as a Scrum Master working on all our concepts. Under his supervision we rolled out the first set of social features on A10.com and I can say he laid the ground work on the portal side for that. On a personal level I have always enjoyed working with him: he's a fun and social person, positive, flexible and always open to discuss new idea's and improvements. Rafał will be sorely missed at SPIL GAMES and I can highly recommend him.
SPIL GAMES
From the moment I started working with Rafal I easily valued and appreciated his Scrum Master contributions and senior expertise. He ran a dedicated team, and due to his on point communication skills and leadership capabilities I could always expect full team commitment. A very reliable, social, professional work experience, which made my life a little easier.
SPIL GAMES
Rafal was one of the key members of our development team and contributed very much to many of our game portal projects. His technical knowledge and interestes are broad and he stays up to date on the latest developments. Knowing Rafal, he will certainly succeed with the new challenges ahead!! I hope to work with him again in the future.

Rafał was very responsible as a Scrum Master (Scrum role). He always tried to improve team effectivenes by introducing XP approach to software development. Rafał has good understanding of big systems and he knows how to simplify and modularize them. He is also a skilled Python programmer.
