// How to build Hyperlocal Food Delivery App for Tier-2 Cities
Tier-2 cities have strong restaurant density but thin aggregator coverage, creating a defensible niche. React Native + Expo ships iOS and Android simultaneously, critical for a two-sided marketplace. Redis + BullMQ handle the order state machine reliably — order placement, restaurant confirmation, driver assignment and delivery must never get stuck. Google Maps SDK is non-negotiable for real-time tracking.

## What to build in the MVP
—Customer app: browse restaurants, cart, checkout (UPI/COD)
—Real-time order tracking on map
—Restaurant partner app: accept/reject orders, mark ready
—Delivery partner app: accept delivery, navigation, POD photo
—Admin panel: restaurant onboarding, commission config, payouts
—Push notifications at every order state transition

## Engineering risks to plan for
!Three separate apps (customer, restaurant, driver) triple QA effort — budget for it explicitly.
!Google Maps pricing can spike unpredictably; implement viewport-based loading and cache tile responses.
!Apple review rejects apps with real-money transactions that bypass IAP — structure payments through Razorpay correctly.
