POMPKINS Food iOS

View on App Store →

My Role

Sole iOS developer — designed and built the entire native app from scratch. The app is the consumer-facing mobile client for the POMPKINS food ordering platform, published on the App Store and handling the full ordering lifecycle from discovery to delivery.

What I Built

• Home & discovery — merchant feed with categories, spotlight sections, and nearby merchant map (Google Maps)
• Ordering flow — merchant detail, menu browsing with item options, cart management, checkout, and Reservepay payment integration
• Real-time order tracking — live status updates via SSE with automatic reconnection and exponential backoff
• Live Activity Widget — order status on the Dynamic Island and lock screen throughout the delivery lifecycle
• Multi-auth — OTP (phone + SMS), LINE, Google, and Apple Sign In
• PompkinsShorts — short vertical video feed (TikTok-style) embedded in the food discovery experience
• Pomp Pomp chatbot — in-app AI assistant for order help and FAQs
• Address management — saved addresses with Google Maps location picker
• User features — order history with pagination, favorites, reviews, notifications inbox, profile

Technical Highlights

• Clean Architecture + MVVM — features organized into domain modules with protocol-based repositories; @MainActor ViewModels with @EnvironmentObject injection for app-wide state (location, address, session)
• SSE real-time tracking — SSEManager with automatic reconnection and exponential backoff; properly tears down connections during app lifecycle transitions
• Live Activity Widget — WidgetKit integration for Dynamic Island and lock screen order tracking, updating through each delivery stage
• Multi-level API cache — five cache policies (cacheFirst, networkFirst, cacheOnly, networkOnly, networkAndCache) with memory + 7-day disk cache; CachedAsyncImage for image caching throughout
• Auth interceptor — AuthIntercepter automatically refreshes expired JWT tokens on 401 responses, transparent to the rest of the app
• Secure storage — all tokens and sensitive data stored in Keychain via KeychainService; CryptoService encrypts sensitive API payloads; certificate pinning in production
