My experience with Kamil was that of being with a Golang expert. He knew all the greedy details from the language and always had some optimization/refactor suggestions to make. This however, never distracted him from the goal of finishing his tasks on time. Basically speaking, he knew what to do and when - which I think is a great quality many developers I have met missed. He was also very team oriented, and generally speaking an easy person to be with - a developer capable of being in any team thanks to his social skills. I highly recommend him!
