CI/CD

GitHub Actions, GitLab CI, CircleCI, Jenkins, Buildkite — pipelines that ship without burning hours.

Most CI pipelines are 5x slower than they need to be. Cache misses, sequential test shards, container image rebuilds on every run, and matrix bloat are the usual suspects. GitHub Actions is good enough for 80% of teams, but the moment you hit usage limits or need ARM/macOS at scale, the calculus changes fast.

These guides walk through real pipeline configs — caching strategies, self-hosted runners, deployment patterns — that take CI runs from 18 minutes to 4.
