Case Study- How Android Platform @ Reddit learned to stop worrying and embrace DevX
summary
Reddit’s Android platform converts multi-hour builds and week-long PR cycles into local builds measured in seconds or single-digit minutes by issuing M1 laptops, adding sample apps and a custom Reddit Gradle Plugin (RGP) for ~700 modules, and enforcing an opinionated Kotlin/Compose stack; CI optimizations include dynamic sharding that cuts unit test time 46%, fan‑out caching, a slash-command service (SLHub) for retries/cherry‑picks, and a homegrown coverage service—P90 review time halves and the changes prove effective.
