Let me tell you exactly what happened the first time I tried to set up Lambda manually.

Four hours. IAM trust policies I didn't fully understand, ARNs copy-pasted into the wrong fields, an API Gateway that was technically configured but somehow not routing anything correctly, and a deploy that failed with an error message pointing me nowhere useful. I hadn't written a single line of actual business logic yet.

That's when someone on my team mentioned the Serverless Framework. My first reaction was honestly skepticism — another abstraction layer sounded like another thing to learn and eventually fight with. I was wrong about that.

This isn't a "look how clean this tool is" post. It's more like: here's what I actually did to get a Postgres-backed CRUD API running on Lambda, step by step, including the parts that tripped me up.
