It's been a pleasure working with Andrzej during his time as Head of Mobile. His expertise in Flutter and architectures is truly impressive, but it's his leadership skills that truly set him apart. From effectively managing a dynamic team of Flutter developers to spearheading the creation of the architecture and advanced CI/CD pipelines for our app, he's shown he can handle anything. But perhaps most importantly, he's got a knack for translating complex business requirements into actionable technical tasks. I would wholeheartedly recommend Andrzej

Andrzej embodies the qualities of both an outstanding software architect and an exceptional team leader. Working on a project designed by him was not only a pleasure but also a tremendous learning opportunity for me. Andrzej possesses a deep understanding of all the elements that make a mobile app work: clean software architecture, best programming practices, comprehensive knowledge of the underlying technology, as well as continuous integration and delivery, thorough testing, and backend integration.
Moreover, he skillfully balances short-term project needs with long-term goals, effectively minimizing tech debt while still driving the project forward rapidly. Last but not least, he has proven to be a compassionate leader who genuinely cares for his teammates' well-being and growth, always finding time to clarify doubts and assist in addressing bugs or architectural challenges.
