The Challenge
ShopNest was running on a generic Shopify setup that could not handle their flash sales — the site would crash within minutes of a sale going live, costing them lakhs in lost revenue. They also needed advanced inventory management across 6 warehouses.
Our Solution
We built a fully custom PHP/MySQL e-commerce platform with Redis caching, a queue-based order processing system, and a real-time inventory sync engine across all warehouses. The architecture was designed to handle 5,000 concurrent users without degradation.
Key Features Built
- Custom flash sale engine with real-time stock countdown
- Multi-warehouse inventory management with automatic reorder triggers
- Advanced analytics dashboard with 30+ custom KPI widgets
- Razorpay, Paytm and UPI payment integrations
- Automated GST invoice generation and filing reports
- Mobile app for warehouse staff with barcode scanning
Results
The new platform handled their biggest sale ever — 10,000 transactions in a single day — with zero downtime. Conversion rate improved from 0.8% to 3.2%. Monthly GMV crossed ₹2.4 crore within 3 months of launch.
Core Technology Stack
The system was built upon a modern, highly decoupled infrastructure stack designed for absolute security and rapid horizontal scaling.
