I will fix vibe coded app backend, supabase setup, firebase auth, database config
Sammy
About this gig
Your vibe coded app looks finished on the frontend, but the backend is where things actually break. Authentication that silently fails, database sync errors, and missing environment variables are the real reason most AI-built apps crash the moment real users show up.
I fix and set up the Firebase or Supabase backend behind your vibe coded app, connecting your frontend to a stable, production-ready system instead of leaving it running on default settings. Whether your app was built with Lovable, Replit, Base44, or another AI tool, I handle the backend logic that AI tools consistently get wrong.
What I deliver:
- Firebase or Supabase authentication, database, and API setup
- Fixing broken auth flows, sync errors, and connection issues
- Real time features including live data sync and push notifications
- Clean database structure built for scale, not just a working demo
- Frontend to backend connection for React, Next.js, or Flutter apps
- Deployment configuration for hosting, storage, and functions
You get a vibe coded app that actually holds up in production, not just one that runs fine in the editor.

I fix what breaks in AI-built apps. Base44 bug fixing, full WordPress migration, and Capacitor conversion into native iOS and Android apps are my core services, backed by tested handover and full backup before anything is touched. I also handle the backend most vibe coded apps get wrong, setting up Firebase and Supabase authentication, database structure, and API connections so your Lovable, Replit, or Base44 build holds up in production, not just in the editor. Message me your app link and issue before ordering so I can confirm the right approach.

FAQ
Can you fix authentication issues in my vibe coded app
Yes, I diagnose and fix broken auth flows in Firebase or Supabase, including session handling, redirects, and login errors that AI tools often leave unstable.
Do you set up Supabase or Firebase from scratch
Yes, I can set up a brand new Firebase or Supabase project including authentication, database, and storage configured for your specific app.
Why does my vibe coded app work in the editor but break in production
This usually comes from missing environment variables or a backend setup that was never built for real user load, which I identify and fix directly.
Can you connect my frontend to Firebase or Supabase
Yes, I connect React, Next.js, or Flutter frontends to your backend so data flows correctly between the two without sync errors.
Do you add real time features to vibe coded apps
Yes, real time data sync and push notifications can be added to any Firebase or Supabase backend as part of your package or as an extra.
What platforms do you support for vibe coded apps
I work with Lovable, Replit, Base44, Bolt, and other vibe coding platforms, handling the backend regardless of which frontend tool built the app.
How long does a full backend setup take
A full Firebase or Supabase setup with authentication and database configuration typically takes about 4 days depending on complexity.
What does backend setup for a vibe coded app cost
Pricing depends on scope. Small fixes start at $30, with full backend builds and production deployment priced higher based on what is included.
