I will fix react firebase bugs and rescue your ai generated web app
Ruben Cuesta
About this gig
Is your React or Firebase web application showing errors, failing to deploy, or behaving incorrectly after AI-generated changes?
I can diagnose and fix issues in existing React and Firebase applications, including projects created or modified with tools such as Lovable, Bolt, Replit, Cursor or other AI coding platforms.
I can help with:
- React component and state errors
- Firebase Authentication problems
- Firestore queries and permission errors
- Firebase security rules
- Cloud Functions and Node.js errors
- API integration issues
- Protected routes and user roles
- Build and deployment failures
- Admin dashboards and e-commerce functionality
- Bugs introduced after AI-generated code changes
My process includes reproducing the issue, locating the root cause, applying a controlled fix and testing the affected functionality.
Please contact me before ordering if the issue involves multiple systems, payments, external APIs or a production environment.
I work on existing source code. This Gig does not include building a complete application from scratch.

FAQ
Can you fix applications created with AI coding tools?
Yes. I can inspect and troubleshoot existing React and Firebase projects created or modified with AI-assisted development tools, provided that the source code is available.
Do you build complete applications?
This Gig focuses on diagnosing and fixing existing applications. New modules or complete applications require a custom offer.
Can you fix Firebase permission denied errors?
Yes. I can review Firestore queries, authentication state and Firebase security rules to locate the cause of permission errors.
Can you deploy the application?
Deployment assistance can be included when the project uses Firebase Hosting, Vercel or a similar supported platform. Deployment credentials must be provided securely through Fiverr.
Do you guarantee that every problem can be fixed?
I first evaluate whether the issue is reproducible and whether the required source code and access are available. Problems caused by unavailable third-party systems or missing source code may require a separate solution.
