About this gig
Your vibe coding app looked perfect in preview. Then a real user signed up, and anyone who opened devtools could read your whole supabase database, because row level security was never turned on.
I'm a vibe coding expert who hardens half-finished lovable ai, base44, rork, bolt and replit builds into apps that survive real users. I've seen this pattern: RLS left off, keys shipped in the frontend bundle, new tables added with no policy.
Here's what I deliver:
- Fix lovable, base44 and replit ai bugs at the root, not patched symptoms
- Lock down supabase: row level security, auth, and exposed-key cleanup
- Finish unbuilt features, stripe payments, broken signup/login flows
- Stabilise messy ai-generated code into a maintainable web app
- Migrate off lovable cloud lock-in onto your own supabase account
- Ship your lovable saas mvp / ai website right: domains, deploy, secrets
- Turn your lovable dev site into a mobile app: app development for android and ios with react native
- Full takeover when the builder loops and burns credits
I trace failures to the root so they stay fixed.
Send your app link and what's breaking, I'll tell you what's wrong and how I'd fix it before you order.

Your AI-built app looked great in the demo, until real users exposed broken auth, failed payments, deployment errors, and hidden bugs. I specialize in turning Lovable, Base44, Replit, Bolt.new, Rork app, Cursor, and v0 projects into secure, production-ready SaaS apps. I fix Supabase auth/RLS, Stripe, APIs, Firebase, OpenAI, Claude, and n8n integrations, build scalable MVPs with React, Next.js, Node.js, and React Native, and deploy on Vercel. Clean code, secure architecture, fast delivery, and apps built to scale.
FAQ
Which platforms do you work with?
I fix and build apps from Lovable, Bolt, Replit, Cursor, base44 and Emergent, including Supabase backends and database setup.
Can you fix my broken Lovable or vibe-coded app?
Yes. I debug errors, repair broken features, clean up messy AI-generated code and get your app stable and production-ready.
Can you set up or fix my Supabase backend?
Absolutely. I handle Supabase auth, database, RLS policies and edge functions, and connect them properly to your frontend.
Can you turn my web app into a mobile app?
Yes. I convert Lovable/web apps into iOS and Android builds (Capacitor/React Native) with push notifications, ready for the stores.
Do you build apps from scratch?
Yes. I build full MVPs and SaaS apps from your idea, frontend, backend, authentication and payments included.
Can you deploy my app and make it live?
I deploy to Vercel, Netlify, AWS or your host, and set up custom domains, DNS, Firebase and hosting so it launches smoothly.
How fast can you deliver?
Small fixes are often done in 24–48 hours; larger builds depend on scope. Message me first for an honest timeline.
Will I keep ownership of my code?
Yes. You keep full ownership of all code and assets. I work in your repo/account and hand everything back to you.
What do you need from me to start?
Your project link or repo, access to the platform (Lovable, Supabase, etc.), and a clear description of the issue or goal.
Do you offer revisions and support after delivery?
Yes. I include revisions until it works as agreed, plus post-delivery support for related follow-up questions.
