The architecture of the app includes distinct login portals for different user roles, namely the consumer, the chef or meal preparer, and the delivery personnel. This multi-user functionality adds layers of complexity to the application’s design, necessitating robust security measures and seamless user experience design across various interfaces.

At the core of the application is its integration with a sophisticated backend server environment through RESTful APIs. This backend system is crucial as it orchestrates all the application logic, enforces business rules, and manages a comprehensive database. This database houses essential information including the schedules of food preparers, detailed menus with dish descriptions, photographic content, pricing information, and other relevant data entities critical for the operation of the service.

The backend infrastructure is hosted on Amazon AWS, leveraging cutting-edge serverless computing strategies. This setup not only enhances the scalability and reliability of the application but also optimizes operational costs and maintenance overhead, ensuring that the application can handle high volumes of user interactions and data processing with high efficiency and minimal downtime.
