The Challenge
A monolithic Shopify architecture was causing 10-second page loads during flash sales, severely hurting conversion rates.
The Solution
Developed a custom headless storefront with Next.js App Router, statically generating product pages and caching heavily at the edge via AWS CloudFront.
The Impact
"Reduced Largest Contentful Paint (LCP) to under 1.2s, resulting in a 45% increase in conversion during the Black Friday peak."
