Message

At Gotech, on secondment to Sterling Bank Ltd, I lead mobile engineering across Sterling OneBank and the wider consumer application portfolio. I authored the shared Flutter foundation and design system packages, delivered with light and dark implementations across five applications.

At MojPosao — Tau on-line d.o.o., I built the mobile CI/CD pipeline with Fastlane, GitLab CI and Xcode Cloud, and defined the architecture and engineering conventions adopted by the mobile team. I also designed the mobile-facing API layer during a backend re-platforming.

My work has included extending Yendo.com’s mobile product into the browser with Flutter Web and building a deep-linking flow for authenticated payments. I’ve also worked at the native seam with Swift and UIKit, including Onfido integration at Roava (FCMB UK).
