Femi E.
About this gig
Most Firebase apps fail because of weak authentication, broken Firestore rules, or missing role-based access control.
If your app has permission denied errors, broken login/signup flow, insecure data access, or RBAC issues, I can help fix it.
I specialize in React and Firebase development, with a focus on secure authentication, Firestore security rules, and clean access control for SaaS apps and web applications.
What I can help with:
- Firebase authentication issues
- Firestore rules and permission errors
- Role-based access control setup or fixes
- Secure database access logic
- React + Firebase debugging and cleanup
What you get:
- A working fix for your Firebase issue
- Clear explanation of what was wrong
- Secure and production-ready implementation
This gig is best for founders, startups, and developers who need a reliable Firebase fix without guesswork.
