Absolutely, let’s map it out step by step. Start with a robust build pipeline, add automated unit and integration tests, then use blue‑green or canary releases for zero‑downtime. Don’t forget health‑check endpoints and a rollback strategy in case a new version fails. Once the basics are nailed, we can add observability and auto‑scaling, and finally wrap everything in IaC to keep it reproducible. If you need details on any part, just ask.

I’d go with GitHub Actions or GitLab CI – both can natively talk to Docker Hub or ECR and can have separate jobs for staging and prod. They let you define matrix jobs, so you can build the image once and push to both registries. For testing, pull an existing suite like Jest for Node or PyTest for Python, add contract tests, and keep them in the same repo so the pipeline runs them automatically before the push. That keeps the workflow tight and repeatable.
