The Challenge

The client's legacy WooCommerce store suffered from slow loading speeds (over 6 seconds for main images) and regularly crashed during peak marketing sales events. Friction in their multi-page checkout flow led to a high cart abandonment rate (76%) and limited their growth.

Our Solution

We engineered a headless frontend using Next.js hosted on Vercel's global edge network. The frontend fetches data from Shopify Plus APIs via a optimized GraphQL gateway. We consolidated checkout steps into a single-page interactive sheet, preloaded assets using edge routing caching, and styled the UI using modular CSS tokens.

Key Results

  • Accelerated Largest Contentful Paint (LCP) from 6.2s to 1.1s.
  • Achieved a 340% increase in purchase checkout conversion rate.
  • Handled a peak sales traffic event of 120,000 active shoppers without a single error.
