Keeping It Clean

" summary

Badoo rewrites its messenger component using Clean Architecture with MVP and RxJava for threading, in an app with over 100 million installs and ~100k lines of code. The implementation keeps use cases as pure Java, moves caching and network into gateways, and yields an open‑source reference with ~60% test coverage. Developers report steeper upfront work and boilerplate but faster feature additions, easier testing, replaceable implementations, and postponed infrastructure decisions.
