Design Rationale

The Smart Lunch Break Optimizer is designed with a focus on speed, efficiency, and user experience. React Native was chosen for its cross-platform capabilities, ensuring a consistent experience on both iOS and Android. The use of Redux for state management will help maintain a predictable state as the app scales.

The backend is built with Node.js and Express for their performance and ease of use, while MongoDB provides the flexibility needed for storing varied restaurant and user data. GraphQL is implemented to allow efficient, specific data queries, reducing unnecessary data transfer.

Real-time features like wait time updates are crucial for the app's value proposition, hence the integration of Firebase for real-time capabilities. The modular file structure and component-based architecture allow for easy maintenance and scalability as new features are added.

The deployment strategy prioritizes scalability and reliability, using AWS services to ensure the app can handle growing user bases and peak lunch hour traffic. The CI/CD pipeline and blue-green deployment strategy minimize downtime and allow for rapid iterations based on user feedback.
