At Swissquote, I own hands-on delivery and release quality for Yuh, a native Android app for payments, savings, and trading. I work on features, review PRs, and help define the API contracts the app uses with backend and system analysis.

I build custom Claude Code agents and reusable skills to keep implementation consistent and support Yuh’s Jetpack Compose migration. I also coordinate feature scope, estimates, and releases across engineering, QA, product, and financial stakeholders.

Previously, at Aer Lingus, I defined modular MVVM and Clean Architecture foundations and helped modernize a Java codebase to 65% Kotlin. At IBM, I led six Android engineers across enterprise products; at DCS+, I designed and delivered two Android applications from scratch as the sole Android developer.
