Understanding the Core Features of a Food Delivery App

Production- grade delivery app mutt orchestrate multiple subsystems: a customer- facing interface, a restaurant dashboard, and a delivant discotery portal. For this article we focus on thee customer side, which typically included des user registration, restaurant discvery, menu browsing, order placement, real-time tracking, and payment processing. Each of these moles has its own compledifficy and integration requiments.

User Registration and Authentication

Users expect frictionless sign- up. Implement social login (Google, accorde) alongside email / password ande phone number verification via OTP.
