We are modernizing an existing business-critical web application by upgrading a legacy PHP backend and rebuilding the frontend using modern React technologies. The project focuses on improving system maintainability, performance, and user experience while preserving existing business logic and data integrity.

- Design, implement, and enhance RESTful (or similar) API endpoints for frontend consumption
- Improve backend architecture, code structure, and separation of concerns
- Optimize database interactions and overall backend performance
- Implement logging, error handling, and basic monitoring where needed
- Write and maintain unit and integration tests for backend components
Frontend (React):
- Modernize the user experience and interface based on existing functionality and UX improvements
- Rebuild existing application screens using React and modern frontend practices
- Integrate React components with the new or enhanced backend API
- Ensure responsive design and cross-browser compatibility
- Manage application state and data flow efficiently
- Collaborate with backend development to align API contracts and data models
- Maintain clean, reusable, and well-documented frontend code
