Forging the path from monolith to multi-module app
summary
TIER moves a 2018 single-module app into a layered multi-module structure over ~10 months, extracting a Legacy module, a shell layer, feature contract+implementation pairs, and a slim app module; tooling includes a Gradle version catalog, a custom Gradle plugin that enforces dependency rules, a cookiecutter CLI for scaffolding, DI scopes and an RX-relay for navigation events. Result: parallelized builds and an extracted large UI feature, navigation solved with activity/fragment routers, unit-testable routing, rollout in iterative 6‑week cycles with 2‑week cooldowns.
