Design backend for Uber-like ride-hailing service

Design the backend system for a ride-hailing platform similar to Uber. Focus on: - How ride requests are placed and matched with drivers ("order taking"). - How user profiles (riders and drivers) are stored and accessed. - High-level handling of real-time locations on a map (you can keep this part relatively brief). - How the system should handle **peak-hour traffic**, when there is a large spike in ride requests. Assume this is for a mid-level backend engineer role; you do not need to go into low-level configuration details of specific technologies, but you should be concrete about architecture, data models, scaling strategies, and consistency considerations.
