CI/CD Platform Engineering

A book-shaped table of contents for CI/CD platform engineering: pipeline foundations, build/artifact/delivery platforms, GitHub Actions end to end (workflow mechanics through enterprise governance), Argo Workflows, Tekton, Jenkins, release engineering, platform security, observability, reliability, enterprise governance, and MAANG interview preparation — cross-linking existing tech/kubernetes/platform-engineering-fundamentals/system-design notes instead of duplicating them.

6 — GitHub Actions: Pipeline Performance

Covers parallelism, dependency-graph optimization, cache strategy, and artifact-size optimization for faster pipelines.

5 — GitHub Actions: Cache Optimization

Covers dependency caching, cache key and restore-key design, diagnosing cache misses, and the performance tradeoffs of aggressive caching.

2 — Build Optimization

Covers incremental builds, parallelization, dependency caching, and remote build caches as the levers for cutting build time at scale.

4 — Build Reliability

Covers retry strategies, build health signals, diagnostics, and observability practices that keep a build platform trustworthy at scale.
