Modern E-commerce Platform
Scalable online store with advanced analytics and seamless user experience
Project Overview
FashionForward Retail, a mid-sized fashion retailer with 12 physical stores, faced declining in-store traffic and needed to establish a strong online presence. Their existing website was outdated, slow, and didn't support mobile shopping - which represented 65% of their target market.
The challenge was to create an e-commerce platform that could handle flash sale traffic (up to 10,000 concurrent users), integrate with their legacy inventory system, and provide a personalized shopping experience that matched their in-store service quality.
We implemented a headless commerce architecture using modern technologies, allowing for fast page loads, easy updates, and seamless integration with their existing ERP system. The platform included AI-powered product recommendations, real-time inventory tracking, and a mobile-first responsive design.
Key Results
- 245% increase in online sales within 6 months
- 38% reduction in cart abandonment rate through improved UX
- Average page load time reduced from 5.2s to 1.8s
- Mobile conversion rate increased from 1.2% to 3.8%
- Integration with 3 existing business systems (ERP, CRM, POS)
- Zero downtime during Black Friday traffic spike of 15,000 concurrent users

Challenges
What we needed to overcome
Legacy System Integration
The client had a 15-year-old IBM AS400 inventory system that didn't have a REST API. Real-time inventory sync was critical to prevent overselling during flash sales.
Mobile Performance Optimization
Google Core Web Vitals were poor (LCP: 5.2s, FID: 285ms). We needed sub-2-second loads on 3G networks for their mobile-first customer base.
Scalability for Flash Sales
Previous Black Friday events caused site crashes due to sudden traffic spikes. The system needed to handle 10x normal traffic.
PCI Compliance & Security
Previous data breach made management highly security-conscious. Needed Level 1 PCI DSS compliance with tokenized payments.
Solutions
How we solved them
Real-time Sync Architecture
Built a middleware layer with WebSocket connections and message queues that synced inventory every 30 seconds. Implemented a distributed caching strategy with Redis to reduce database load.
Progressive Web App with Advanced Caching
Implemented service workers for offline browsing, image optimization pipeline, and code splitting. Used Intersection Observer API for lazy loading.
Microservices Architecture on AWS
Split monolithic backend into independent services (auth, products, orders, payments) deployed on AWS ECS with auto-scaling.
