Currency Exchange App
A Swiss fintech mobile client where everything had to ship production-grade: a complex multi-step regulated signup (Onfido KYC), four-language localization and signed iOS/Android release pipelines.
Mobile lead on a Swiss fintech currency-exchange app, live in four languages (DE, FR, IT, EN) on both stores. Owned the architecture end-to-end. The signup was a complex multi-step regulated flow with Onfido KYC. Added mobile observability and attribution (Crashlytics, Firebase Analytics, AppsFlyer) and an externalised translations workflow. Ran the iOS/Android release pipelines on CircleCI + Fastlane, later migrated to GitHub Actions.
