About this gig

Seeing "permission denied", "missing or insufficient permissions" or login errors in Firebase? I will fix your Firebase authentication and Firestore security rules fast, and explain what went wrong so it does not happen again.


I build and ship production React and React Native apps on Firebase, so I debug real-world setups, not just tutorials.


What I fix:

Email, Google, Apple and phone auth errors

Firestore security rules (permission denied, unsafe open rules)

Composite index and query errors

Firebase Storage rules and upload errors

Admin SDK and Cloud Functions issues

Role-based access (admin / user)


How it works:

1. Send me the error message or screenshot, plus your rules and code.

2. I find the root cause and fix it.

3. You get the working code and a short explanation.


Not sure what is wrong? Message me before ordering and I will tell you if I can help.
