I met Szymon in 2016 when one of my big clients (Play) required a mobile application crucial to their new spin-off project (Folx). Szymon had introduced himself as the main contact to the development team but he turned out to be so much more.
Without any hesitation, he is the best project manager I have ever met, and I did meet quite a lot of them in many companies on three continents.
Whether you want him on your side or as a partner you should be very happy. As a partner he delivers not only in his PM role but he has a lot of technical knowledge as well. As a “team manager” besides the skills listed above he has a unique ability to take care of both the team’s morale and the value delivered to the client.
