    I have been working with Piotr for the last 10 years. I have consistently been impressed with his professionalism, leadership skills, and dedication to providing excellent customer service. Piotr has a talent for inspiring his team to perform at their best, and he has a natural ability to communicate effectively with clients and colleagues alike. One of the things that I particularly appreciate about Piotr is his ability to handle difficult situations with grace and ease. He is a calm and collected presence even in the face of challenging customer inquiries, and he has an uncanny ability to find creative solutions to complex problems. His strongest skill is process thinking and ability to solve problems. He is always looking for ways to improve processes and systems, and he takes a proactive approach to identifying and addressing potential issues before they become problems.

    Łukasz Przybyłowicz

    I have been working with Piotr for over 7 years, and the cooperation has always been very fruitful. His knowledge and experience go far beyond IT. This allows him to turn visions into concrete solutions, without being attached to specific tools that much. At the same time, Piotr has an in-depth knowledge of IT systems and the ability (or perhaps the necessity) to learn quickly. Thanks to this, he is not afraid of experimenting and remains flexible when solving problems. On the other hand, he has the ability to pass on the knowledge, so each meeting with him leaves you wiser.
