None. I work in consulting specializing in AWS Architecture + app dev. All of my projects over the last 6 years have been green field - empty AWS account + empty git repo.

I’ve been using Codex and Claude code over the past 6 months. They both do pretty well creating well structured normalized database schemas for both RDMS databases and single table design + appropriate GSIs with enough (business context). But they both have are suboptimal architecture and ETL designs.

I know AWS very well (trust me). But I would never go in blind for instance doing a green field implementation on Azure trusting AI.
