Web App Fixes & Dashboard Completion

I'm working on a web app using lovable.ai, an AI service that creates web apps from prompts. I've run into a few issues and need help from an expert who can fix errors and complete my web app dashboard.

Here are the specific problems I've been facing:

- Loading issues
- Data display errors
- Functionality problems

Additionally, there are a couple of features that are still incomplete or missing:

- Data visualization
- Settings management

I prefer someone who can start immediately and has experience with web app development and debugging. Ideally, you can complete this project within 2-3 days. The design layout for the dashboard is a standard template, so no custom design is needed.

Skills needed:
- Web app development
- Debugging
- Data visualization implementation
- Settings management finalization
