Executive Project Context

ShopKart, a rapidly growing online lifestyle store, was losing revenue due to a slow legacy monolith that crashed during peak promo sales. codeYB re-architected their entire digital storefront into a headless Next.js 16 platform backed by Node.js microservices and automated warehouse stock synchronization.

⚠️ Initial Technical & Operational Challenges

1. Slow Legacy Storefront & Ad Traffic Bounce

4.8s initial render speeds caused a 58% bounce rate during Instagram ad campaigns.

2. Complex 4-Step Checkout Abandonment

Mandatory account creation and multi-page checkout forms resulted in 65% abandoned carts.

3. Overselling & Inventory Desynchronization

Manual stock entry across 3 regional warehouses caused stockouts and customer complaint tickets.
