I will fix and scale your ai generated app to production
Johan Garcia
Level 2
About this gig
Is your AI generated app stuck in a loop, throwing build errors, or unsafe to launch?
Tools like Cursor, Lovable, v0, and Bolt are incredible for prototyping, but they often produce fragile spaghetti code, exposed API keys, and insecure databases that cannot scale.
I am a Level 2 Full Stack Developer with nearly 10 years on Fiverr. I step in as your Senior Engineer to audit, secure, refactor, and stabilize your AI prototype into production ready software.
What I Fix & Optimize:
- Build & Runtime Errors: Fix hydration bugs, broken state, and Vercel deployment crashes
- Supabase Security: Implement airtight Row Level Security (RLS) and clean PostgreSQL schemas
- API & Secret Protection: Move exposed keys to secure backend routes and edge functions.
- Architecture Refactoring: Clean modular Next.js (App Router), TypeScript & Tailwind CSS.
- Payments & Auth: Fix Stripe subscriptions, webhooks, and Google/Email authentication.

FAQ
Which AI builders and tools do you support?
I work with projects generated by Cursor, Lovable.dev, v0.dev, Bolt.new, Replit, ChatGPT, Claude Artifacts, or Windsurf. Whatever tool generated your code, I can audit, fix, and stabilize it.
How do I share my codebase safely?
You can invite my GitHub/GitLab account as a collaborator or share a ZIP export. For Supabase or Vercel, you can invite my email as a team member or provide temporary environment credentials.
Why is Supabase Row Level Security (RLS) so important?
Most AI tools generate Supabase tables with RLS disabled. This allows anyone to inspect your network calls and read, edit, or delete your entire database! I write strict PostgreSQL RLS policies to ensure users can only access their own data.
Can you fix build errors preventing Vercel deployment?
Yes! AI generators frequently create TypeScript type conflicts, improper server/client component boundaries, or missing environment variables. I resolve all build blockers so your app deploys cleanly to Vercel.
Is my project and source code kept confidential?
100% yes. As a Level 2 Seller with nearly 10 years on Fiverr, your code and business idea are strictly confidential. I am also happy to review and sign an NDA if requested.
