Building a Scalable Android Platform
summary
Deutsche Bank consolidates multiple mobile banking, 2FA and trading products into a single, modular Android platform that started in 2019 and evolves over eight years. Core is a white-label app with feature modules (authorization, transfer, brokerage) plus a foundation of networking, storage, navigation and a centralized icons library. Builds use four dimensions (target, app type, brand, build type) and GitHub Actions/Gitflow CI to produce artifacts for every flavor. Runtime and compile-time runtime toggles control rollout; stack: Kotlin, Compose, Retrofit, Coroutines, RxKotlin, Dagger2/Hilt. Features deployable and in production for multiple brands.
