I've had the pleasure to work with Krzysztof in Opera Software. He is a skilled and hard working developer, who is always full of great, creative ideas. Krzysztof is very energetic and has an endless supply of positive energy which makes him a valuable member of any team.

I remember Krzysztof as a very helpful person with a positive attitude who always shares constructive feedback with others. He was very active during ceremonies/meetings, sharing his knowledge across the whole team. During our work in STXNext, Krzysztof created a cool build system that was very, very helpful in daily work. I always heard from other developers, that Krzysztof writes good, clean, and well-designed code, and his solutions always meet given ACs. He was also supporting less experienced coders. I value Krzysztof's quality highly. in my opinion, he meets all requirements for a full-stack developer. What is most important, Krzysztof always respects the client and the project.

Krzysztof is a really smart guy. He learns very fast, always finds time to help others. In his work, he pays a lot of attention to details. I really enjoyed to work with him.
