Summary
Krzysztof Mamak is a self-taught Flutter developer with eight years of engineering experience, currently building a major Polish bank’s mobile app at LeanCode. He brings full-stack comfort—commercial work with Flutter on mobile front-ends and NestJS, Node.js and Spring on back-ends—plus a history of shipping tested products from internships to production. Previously he led mobile and backend efforts at NaviParking, wrote unit/widget/integration tests, and transitioned from a geodesist role where he developed strong measurement, precision and documentation habits. Based in Rybnik, Poland, he combines practical engineering discipline with a curiosity for mobile technologies and an unusual personal interest in the history of Russia and the Soviet Union, which informs a thoughtful approach to learning from past systems.
