One Repo, Three Languages: Mastering Polyglot Monorepo Architecture

Polyglot monorepos eliminate coordination friction when frontend, backend, and ML teams use different programming languages, using Protobuf as the single source of truth for service contracts. By orchestrating multiple workspace managers (pnpm, uv, Go) from a shared root configuration, teams maintain full autonomy while preventing contract drift and reducing inter-team friction. This architecture is critical for organizations scaling across language boundaries without sacrificing infrastructure efficiency.
