To address these issues, the Protein Shop app was developed using HTML, CSS, and jQuery for the frontend and PHP with the Flight framework for the backend. The frontend and backend communicate via AJAX requests, ensuring a smooth and responsive user experience. A user-friendly interface is provided, and real-time notifications are sent when orders are placed and when they are shipped.

The application follows a system where the frontend manages presentation and interactivity, the backend processes requests and communicates with the database, and the database stores all product, user, and order information.
