01Overview

Overview

Northwind ran a legacy WooCommerce stack that buckled under catalog growth. We rebuilt the storefront on Next.js + WooGraphQL with a Redis-backed edge cache, while keeping Woo as the source of truth.

02The problem

The problem

The PHP-rendered storefront held a p75 TTFB of 1.4s and degraded sharply during sale events. Catalog pages timed out, and search was unusable above 50k SKUs. Conversion stalled despite increasing ad spend.

03The solution

The solution

  • Headless storefront on Next.js 14 with React Server Components.
  • WooGraphQL contract with a typed schema and persisted queries.
  • Redis-backed cart, session, and product caches at the edge.
  • Atomic deploys via Vercel with preview environments per PR.
