Scaffold a production monorepo: Nx vs Turborepo decision, workspace structure, shared packages, CI matrix builds, versioning strategy (fixed vs. independent), and dependency graph visualization.

Scaffold a production-ready Firebase project: Firestore data modeling, Security Rules, Cloud Functions v2, emulator suite, hosting config, and CI/CD. Covers auth flows, subcollection design, and multi-environment strategy.

Scaffold a production-parity Docker development environment: multi-service Compose, volume mounts, networking, health checks, dev containers, and secrets management. Eliminates "works on my machine" at the infrastructure layer.
