Flutter E-Commerce App - ₹2 Crore Monthly Revenue in 4 Months
A Delhi-based D2C fashion brand needed a mobile-first shopping experience. We built a Flutter app with Razorpay integration and a custom recommendation engine that drove ₹2 crore in monthly revenue within 4 months.
The Challenge
The client was running entirely on their website - no mobile app. 78% of their traffic was mobile but the website's mobile conversion rate was 0.8%. They had lost 3 major sale events to site crashes under traffic load. They needed a native app experience on both iOS and Android within 12 weeks.
The Solution
We built a Flutter app with a custom product catalog, AI-powered size recommendations (based on past purchase history), and a frictionless 2-step Razorpay UPI checkout. A Node.js backend with Redis caching handles flash sale traffic spikes without downtime. Firebase Crashlytics and Analytics provide real-time monitoring.
