Design Rationale

The choice of React Native for the frontend allows for efficient cross-platform development, reducing time-to-market and maintenance costs. Node.js on the backend provides a JavaScript-based full-stack solution, enabling code sharing and improving developer productivity. PostgreSQL was selected for its robust relational data model, which is well-suited for the complex relationships between users, trips, and bookings.

The modular file structure and use of Redux for state management promote scalability and maintainability as the application grows. The implementation plan prioritizes core functionality early, allowing for user testing and feedback to inform later stages of development. The deployment strategy leverages cloud services for reliability and scalability, with a focus on monitoring and security to ensure a stable and trustworthy application for users.
