Available to hire
Hi, I’m Michał Bartnik, a Flutter-focused mobile software developer with a strong background in cross-platform applications (Android and iOS). I enjoy building scalable, maintainable code and architecting robust mobile solutions that work offline and integrate with maps and cloud services.
In my projects I’ve migrated legacy apps to modern, feature-driven architectures and collaborated with teams to deliver high-quality user experiences. I’m always eager to mentor teammates and learn new tech to deliver great results.
