I will fix bugs, refactor and secure your vibe coded website or app

About this gig
Your app works. Until it doesn't.
Lovable, Bolt and Cursor get you to a working prototype fast. What they do not give you is safe auth, sane database rules, or code a second developer can pick up. That is the part I fix.
WHAT I FIX
- Bugs and crashes the AI could not debug itself.
- Exposed API keys, weak authentication and unsafe database rules.
- Supabase row level security that lets users read each other's data.
- Slow queries, N+1 problems and bloated bundles.
- Duplicated, unstructured code refactored into clean modules.
- Broken deploys, environment variables and build pipelines.
- Missing error handling, validation and tests.
WHAT YOU GET
A working, secure, documented codebase, a written report of every issue found and fixed, and clear guidance on what will break next as you scale.
STACKS I WORK IN
React, Next.js, Vue, Node, Express, Python, Supabase, Firebase, PostgreSQL, MongoDB, Tailwind and Vercel.
Send me your repo or app link before you order and I will tell you honestly whether it needs a fix or a rebuild.

FAQ
My app was built with Lovable. Can you still work on it?
Yes. Lovable is my main platform, and I also work with code from Bolt, Cursor, Replit, Base44 and v0. A GitHub repo, an export, or a connected project all work fine.
How do I know if I need a fix or a full rebuild?
Send me the repo or app link and I will assess it free before you order. If a rebuild is genuinely cheaper than patching, I will tell you that instead of selling you the bigger package.
Is my code and my idea kept confidential?
Yes. I do not reuse, publish or share client code, and I am happy to sign an NDA before you send anything over.
Can you add new features while you are in there?
Yes, as a custom offer. Fixing comes first though. Adding features on an unstable base is how these projects end up broken twice.
What do you need from me to start?
Your repo or export link, a live URL if there is one, and a list of what is broken or worrying you. Hosting and environment variable access too if the deploy needs fixing.
