Overview
What this challenge is about.
Set up Nx (or Turborepo) for affected-graph computation. Configure remote build cache (S3-backed) so cached steps skip across runs and developers. Parallelize jobs in GitHub Actions matrix per affected service. Add per-service deploy jobs that only run if the service is affected, gated on green tests for affected services only. Measure baseline (47 min) vs new pipeline on a 50-commit replay (real PRs from history). Deliver the .github/workflows files, Nx config, benchmark report, and a 5-page playbook on what to do when cache misses spike.
The Brief
What you'll do, and what you'll demonstrate.
Cut monorepo CI from 47 minutes to under 12 minutes commit-to-deploy with affected-only builds + tests across 14 services.
Earning criteria — what you'll demonstrate
- Use a monorepo build tool's affected-graph to skip unaffected work
- Configure remote build cache that is shared across CI and developer machines
- Parallelize CI jobs with matrix strategies bounded by runner concurrency
- Diagnose cache-miss spikes and adjust hashing inputs accordingly
