AI builders make a good demo fast. Then real users arrive, and logins, data and payments start to break. I take prototypes built with Lovable, v0, Bolt or Claude Code and turn them into apps that hold up: a real backend, a secure database, proper auth, and a clean deployment. I keep the screens you like and fix what is underneath. First I review your code and tell you plainly what is safe to keep and what needs a rebuild.
