Use when setting up CI/CD for a new project, optimizing slow pipelines, creating reusable workflows, or implementing complex deployment strategies like canary or blue-green.

Examples

Full CI/CD pipeline

Create a complete test → build → deploy pipeline

Create a GitHub Actions workflow that runs tests, builds a Docker image, pushes to ECR, and deploys to ECS on merge to main

Optimize slow pipeline

Speed up a CI pipeline that takes 20+ minutes

My CI takes 25 minutes — help me add caching, parallel jobs, and skip conditions to bring it under 8 minutes
