Inside a 3-app Turborepo monorepo: parallelism, caching, and CI that stays fast

Short summary

Author optimized a 3-app monorepo using Yarn workspaces and Turborepo to achieve 2m 30s CI times through intelligent task caching and parallelism. Monorepo benefits include atomic refactors, synchronized design tokens, and unified PRs, but demand strict discipline around package boundaries and dependencies. Turborepo was chosen over Lerna for superior build caching, task orchestration, and Vercel's free remote cache.
