QuickBite — Food Delivery App
A full-stack food delivery app with real-time tracking, in-app payments, and restaurant management dashboard that hit 100K downloads in 90 days.
The full picture
QuickBite set out to build a premium food delivery platform for the tier-2 city market — an underserved segment where Zomato and Swiggy have high commission structures. The platform needed real-time order tracking, seamless payments, and a restaurant management portal, all delivered in 16 weeks.

Existing food delivery apps in tier-2 cities charged restaurants 25-30% commission, making profitability impossible for independent restaurants. QuickBite needed to build a lower-commission alternative that was technically competitive with Zomato and Swiggy while being operationally lean.
How we solved it
We built a three-sided platform — consumer app, restaurant portal, and delivery partner app — on a unified React Native codebase with a Node.js backend. The architecture used WebSockets for real-time order updates and Google Maps for route optimization, delivering a premium experience at a fraction of the typical development cost.
How we built it, step by step
Product Discovery
Market research, competitor app teardown, user interviews with 30 restaurant owners and 50 consumers.
Architecture & Design
System architecture design, API contract definition, and complete UX/UI design for all three apps.
Core Development
Consumer app, restaurant portal, and delivery app built simultaneously by three parallel tracks.
Integration
Payment gateway integration, real-time tracking, push notifications, and third-party service connections.
Testing
Load testing with 1,000 simulated concurrent users, UAT with 20 beta restaurant partners and 100 consumers.
Launch
Staged city-by-city rollout with aggressive referral program and restaurant onboarding campaign.
Inside the product
Real problems, real solutions
Real-Time Tracking at Scale
Ensuring real-time location updates for hundreds of simultaneous deliveries without server overload.
Implemented WebSocket connections with Redis pub/sub for location broadcasting, and a delivery partner location compression algorithm that reduced data transmission by 60%.
16-Week Timeline
Building three distinct apps plus a backend in 16 weeks is extremely aggressive.
Created a single shared component library used across all three apps, and used OpenAPI spec contracts to allow frontend and backend teams to work in true parallel.
UPI Payment Integration
UPI deep linking and callback handling is complex and poorly documented.
Built a payment abstraction layer that handles UPI, Razorpay cards, and COD uniformly, with robust retry logic and payment state reconciliation to handle network failures.
Dhivin built three apps and a backend in 16 weeks without cutting a single corner. The code quality is exceptional — our in-house team took it over seamlessly. The app reviews speak for themselves.
