React SPA Developer Needed for Assessment

I need a React software developer to evaluate and improve a Single Page Application (SPA) I inherited. The primary functionality involves user authentication and authorization, data visualization and reporting, and content management and publishing.

Key Tasks:
- Assess the current state of the application
- Troubleshoot and fix any issues


Ideal Skills:
- Proficiency in React
- Experience with SPA development
- Strong troubleshooting skills
- Knowledge in user authentication, data visualization and content management

This project requires a detailed evaluation of the application's condition, so experience in assessing and improving existing software is a plus.

I need to know what would make this operational.

All I want is for someone to try to start the code and see if it will build without errors
