About this gig

Having Firebase errors in your web app?

I will troubleshoot and fix common Firebase Authentication, Firestore, permission, configuration, and JavaScript integration issues in your existing web application.

I can help with:

Firebase login and signup errors

Authentication problems

Firestore read and write issues

Permission denied errors

Basic Firestore security rule issues

Data not loading or saving

Firebase configuration problems

JavaScript and Firebase integration bugs

AI-generated or vibe-coded Firebase app issues

Broken features connected to Firebase

I focus on identifying the real cause of the problem and making focused fixes without unnecessary changes.

Please contact me before ordering if your project has multiple issues or requires major changes so we can confirm the correct scope.
