Building a Database Performance Testing Tool With AI: The Honest Breakdown

This is a build log, not a product launch. The author used AI to write the bulk of the code for a database performance testing tool and documented where the workflow held up and where it produced garbage. The value is in the specifics of the breakdown — which kinds of tasks the AI handled cleanly and which required heavy human intervention or produced subtly wrong results. For anyone who has already bought into AI-assisted development but wants a calibrated read on where the floor is, this is a useful data point. It is not a tool you can go install. The database performance angle is secondary; the real subject is the AI-assisted development experience. Reservation: it is one developer's experience on one project, so generalizing the findings takes some care. Worth reading if you are evaluating whether to lean on AI code generation for infrastructure tooling specifically, where correctness is harder to eyeball. -> Best for: technical PM or solo founder evaluating AI-assisted development for backend or infrastructure work
