Summary
🤩
Rockstar🎓
Top SchoolTomasz Olszewski is a seasoned Senior iOS Developer with over a decade of mobile experience and a long background in web and PHP-based APIs dating back to 2006. Currently driving core features for the official mBank iOS app, he blends hands-on Swift (including RxSwift, MVVM/MVC and SwiftUI) with deep backend knowledge in Symfony/Laravel gained from running his own software shop. He has led teams of iOS engineers, automated CI/CD pipelines, and championed robust testing and code quality practices across multiple commercial products. An early Zend PHP5 certified engineer in Poland, Tomasz is comfortable moving between mobile UI, offline sync and server-side API design—an uncommon full-stack perspective for an app-focused developer. He’s equally at home rebranding and directing product efforts as he is solving low-level synchronization and networking challenges for large-scale apps.
