Writing code is no longer the hard part. Running it in production is

AI made writing backend code much easier.But in real projects, the hardest questions are still unsolved:- How do you structure a project for a team? - How do you build CI/CD with real rollback? - What does a safe migration strategy look like? - How do you set up observability before things break? - How do you actually debug production?I spent a long time figuring this out across different projects, and couldn’t find a single place that connects all of it together.So I built a simple Todo API as if it were a real production system.The focus is everything around the code: CI/CD, Terraform on AWS, observability, release automation, rollback.Not a boilerplate. A reference with reasoning behind every decision.Would love feedback from people who've dealt with this in production.
