" summary

Capital One explains concrete steps to scale mobile: codebases with 1.7 million lines of code, ~150 developers per platform and ~17 PRs/day move from dozens of repos to a monorepo (iOS down to 11 repos, Android to 1 repo), break the app into ~100 feature plugins, adopt a unidirectional reactive store for easy unit testing, use Gradle optimizations, a multi-merge CI job and partial-source local builds, and migrate parts of the build graph to Bazel to cut build and merge pain.
