TL;DR — DoorDash Delivery

Design a food delivery platform similar to DoorDash that connects restaurants, delivery drivers (dashers), and customers. The system must handle real-time order management, intelligent dasher assignment, delivery time estimation, and order batching to optimize delivery efficiency while ensuring food arrives hot and fresh. Key features: Customer browses nearby restaurants, views menus, and places orders. Restaurant receives orders and updates prep status in real-time.
