Piotr is a great developer and highly skilled His work is always high quality and delivered on time. It's a pleasure to work with him.

— Kamil Rutkowski

As a programmer, Peter is distinguished by two qualities that certainly deserve recognition. The first is to look for the best, targeted solution. He tries to carry out tasks in such a way as to prepare functionality 'for years', not 'for a moment'. The second is his understanding of the business and his ability to translate technology into business and vice versa. I heartily recommend Piotr as an experienced programmer.
