Endless tools promise perfection, but most teams drown in complexity. As a developer solving real problems, what’s the leanest GitHub Actions/Docker stack monorepo or polyrepo, testing pyramid, deploy stages, monitoring basics that gets code to production safely in <10min, handles 10 engineers, and scales to enterprise without rewrite?

Security baked in from commit:
lint (ESLint) → SCA (Dependabot) → SAST (CodeQL) → Docker scan → deploy
Secrets: GH OIDC → no long-lived creds. RBAC: branch protection + CODEOWNERS. Canary deploys: 10% traffic first (Argo Rollouts guide: https://argoproj.github.io/argo-rollouts/). Alert on: 5xx errors, deploy drift. Prod-ready Day 1.
3-stage GitHub Actions MVP:
test -> build -> deploy
Dockerfile: Node → production (alpine). Polyrepo until 50 devs. Monitoring: Sentry + UptimeRobot free tier. Scales to 100 deploys/day.
