Wojciech is very focused on design and proper documentation. I worked with him on an R&D testing platform where he had a major and decisive role in sketching the implementation. His ideas were far-reaching, exceeding what product owners expected. Wojciech is exceptionally intelligent, has very strong background in Computer Science, Math, programming languages theory, but is also quite fascinated in genetics and Bioinformatics. Expect him to shine in non-trivial projects where thinking outside of the box is valued. Regardless of having long experience, he is very up to date with recent technology and trends. Very passionate software developer determined to deliver high quality software. Also he is not afraid to express his feelings, doubts and uncertainties, even in the presence of upper management. Wojciech is capable of writing great software in pretty much any technology as long as the problem is interesting. He can also be a technical mentor and team leader, as long as he can get his hands dirty in development, testing and deployment.
