Your app works in a demo and falls over with real users. This is the gap between the two.

AI builders get you to something real fast. What they don't give you is what happens at 500 concurrent users, or when someone finds the auth endpoint, or when the database has 100,000 rows instead of 40.

I take what exists and make it hold: proper auth and session handling, error handling and monitoring, database indexes and query performance, CI/CD and a staging environment, and load testing so you know the actual ceiling before your users find it. Deployed on AWS or Vercel, your accounts, your ownership.

Most of the generated code stays. I rewrite the parts that won't survive, which is faster and cheaper than starting over, and I'll tell you honestly in the first call which parts those are.

From you I need repo access, your current hosting details, and a sense of the traffic you expect.
