I will debug firebase authentication and firestore issues in react
Malik Zain
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.

FAQ
Do you need access to my Firebase project?
Not always. For small fixes, your code and rules are enough. If I need access, you can add me with limited permissions and remove me when the order is done.
Can you fix "missing or insufficient permissions" in Firestore?
Yes. This is one of the most common issues I fix. It is usually a rules problem, an auth state problem, or a query that does not match the rules.
Will you make my rules secure, not just "allow all"?
Yes. I will not leave your database open. I write rules that match your app's roles and data.
What if I am not sure what the problem is?
Send me a message with your error before ordering. I will tell you if it is something I can fix.
