CI/CD for Beginners

Two weeks after you deploy, you need to make a change and you're trying to recall the steps or find the agent session you used to ship it. Manual deploys, CLI commands from memory, agent tokens spent on something a file could handle. I replaced all of that with one workflow file and a git push. CI/CD from scratch, built incrementally on a real app. I start with a Lambda function (Decide For Me, picks a random option from a list) deployed manually, then add automation one layer at a time: a GitHub Actions workflow for continuous deployment, tests for continuous integration, and then I deliberately introduce a bug to show what happens when the pipeline catches a failure before it reaches production.
