Senior🎓
Top SchoolMarcin Chudy is a Senior Software Developer based in Warsaw with 11 years of experience and a specialist focus on Flutter mobile development, leading Flutter teams for over five years. He combines deep hands-on skills across mobile stacks—Flutter, React Native, iOS/Android—with a track record of improving platform stability and testability, notably contributing camera and auth fixes in prominent open-source repos. At Leancode he ships production Flutter apps while earlier roles at Netguru and Epicode sharpened his cross-platform and CI/E2E testing expertise. Marcin pairs academic rigor from an MSc in Computer Science with practical engineering: he has fixed device-specific crashes, refactored test suites to remove fragile dependencies, and added localization/customization hooks in native dialogs. He’s as comfortable mentoring teams and running event-storming sessions as he is diving into native Android or iOS code to resolve tricky bugs.
