Zupper: Modular On-Demand Food Delivery Platform
High-speed food ordering starter ecosystem built with React Native Expo, Razorpay payments, live Google Maps tracking, and merchant administration.
Key Project Metrics and Results
01 / System Overview
Background & Problem Space
Zupper was conceived as a modular, turnkey food delivery mobile platform for emerging restaurants and hyperlocal courier services. It provides a ready-to-scale delivery foundation with rapid restaurant discovery, intuitive cart workflows, integrated payments, and live courier tracking.
02 / Technical Challenge
Core Bottlenecks
Launching an on-demand delivery app requires juggling map SDKs, location permissions, real-time order status websockets, and checkout payment gateway SDKs without bloating app bundle size or causing battery drain.
03 / Engineering Solution
Architectural Approach
We built a streamlined React Native application backed by Firebase push notifications, Razorpay payment processing, and Google Maps autocomplete and route polylines.
04 / Architecture Breakdown
Key Engineering Decisions
Modular mobile-first architecture built with React Native and Expo, utilizing Zustand for state management, TanStack React Query for data caching, and native payment modules.
Zustand Lightweight State Store: Ultra-fast cart manipulations and delivery address selections with zero re-render overhead.
