Design a Ride-Sharing Service like Uber or Lyft

Functional Requirements:

• Riders can create accounts, log in, and manage their profiles.
• Riders can request rides by specifying pickup and drop-off locations.
• Drivers can register, log in, and manage their profiles and vehicle information.
• The system matches ride requests with available drivers based on proximity.
• Real-time trip tracking for both riders and drivers during an active ride.
• Riders can view fare estimates before confirming a ride.
• Riders can pay for rides via supported payment methods (e.g., credit card).
• Both riders and drivers can rate and review each other after a trip.
• Riders and drivers can view their ride/trip history.

Non-Functional Requirements:

• The system should be available 24/7 with minimal downtime.
• Response time for ride requests and matching should be low (ideally < 2 seconds).
• The system must scale to handle high traffic during peak hours.
• User data and payment information must be securely stored and transmitted.
• The system should be reliable, ensuring that ride requests and payments are not lost.
• Basic support for mobile clients (iOS, Android) and web clients.
