Fix Database Access on React App

I am currently facing database access problems in a React web application that I developed which requires resolving by a skilled full stack developer with proficiency in MongoDB. The application is having issues with:

- Reading data from the database specifically, the app doesn't work well when retrieving data.

The potential freelancer must be experienced in:
- React web application development
- MongoDB database operations particularly with data reading procedures
- Troubleshooting and resolving database access problems

Consequently, am searching for a freelancer to troubleshoot and rectify this issue to make the application operational beyond the current sandbox environment.
