Summary
🤩
Rockstar🎓
Top SchoolBart Selwesiuk is a mobile-first engineer and founding lead for Orb, bringing 9 years of experience building cross-platform apps with a strong focus on Flutter and Web3-powered social experiences. He combines product-facing execution—shipping mobile, web and desktop clients, native integrations and CI/CD pipelines—with hands-on backend work (NodeJS, Serverpod) and payments/auth flows. A frequent open-source contributor to Flutter, Bart added web camera support, zoom/flash controls and helped improve the official News Toolkit and flutter_svg, contributions that earned recognition during the Flutter 2.8 cycle. He has led small teams at Very Good Ventures, delivered consumer-grade apps like the Hamilton app and built resilient, test-covered samples such as the slide puzzle for Flutter Puzzle Hack. Based in Warsaw, he blends formal AI/algorithms training from DTU with practical experience in accessibility, responsive UI and ad/analytics integrations. Colleagues describe him as a dependable engineer who prefers shipping polished UX and reusable platform components over one-off hacks.
