Full-Stack Web Application for Data Analysis and Reporting with Ai Insights

We are seeking an experienced full-stack web developer to build a robust data analysis and reporting platform. The application will enable users to upload CSV or Excel files, which will then be automatically cleaned and processed. The core functionality includes generating interactive dashboards featuring various charts and insights.

Key features required:
- User authentication (login and registration).
- Role-based access control to manage user permissions.
- A simple, intuitive admin panel for system management.
- Interactive dashboards displaying key metrics and visualizations such as bar charts, line charts, and pie charts.
- Filtering capabilities for data by date or category.
- Export functionality for reports to PDF and Excel formats.
- Integration of basic AI-based insights or trend detection to enhance data analysis.
- A clean, modern, and responsive user interface design.
- The system must be designed for scalability, security, and optimal performance.
- Deployment to a cloud platform (e.g., AWS, DigitalOcean).

The backend should be developed using Python, with a preference for Django or FastAPI frameworks. The frontend must be responsive and built with modern web technologies, such as React. The ultimate goal is to deliver a professional, production-ready analytics platform suitable for small and medium-sized businesses.
