Crave — a complete food delivery app for iOS AND Android

Crave is a polished, DoorDash-inspired food delivery app for iOS and Android, built with Expo (React Native) on a mock / local-only backend — no servers, no API keys, no sign-ups. Browse a location-aware home feed, explore restaurants and menus, customize items with live pricing, and run a full cart → checkout → live order-tracking loop, all from realistic seed data served through a single typed mock API that simulates network latency. Everything persists on-device, so the whole experience works offline and is demoable instantly. When you outgrow mock/local, you swap one module for a real backend (Supabase / Firebase / REST) without touching a single screen. Tech stack: Expo Router · TypeScript (strict) · Reanimated 4 · Zustand · expo-image · Zod · AsyncStorage.

• 🍔 Home discovery — location header, search, round category row, multi-select filter chips, and feed carousels (Fastest near you, Offers for you, Popular) with pull-to-refresh and skeleton loaders.
• 🔎 Smart search — 250ms-debounced queries, recent searches, suggested cuisines, and a filter sheet for sort / price / cuisine.
• 🍽️ Restaurant detail — parallax collapsing hero with a sticky category strip that scroll-syncs to the menu sections.
• 🧩 Item customization — radio/checkbox option groups with live price deltas, required-option gating, quantity, and a fly-to-cart animation.
• 🛒 Cart & checkout — grouped lines, swipe-to-delete, promo codes, a full price breakdown, and mock address / time / payment / tip — all in integer minor units.
