01Situation
The problem
Quarry's Shopify theme was eight apps deep and slow as molasses on mobile — where 78% of their traffic lived. Conversion on phones was less than half of desktop.
02Playbook
The approach
- 01Migrated the storefront to a headless Next.js + Shopify Storefront API stack.
- 02Killed five redundant apps, replaced their functionality with native code we own.
- 03Rebuilt PDP, cart, and checkout with Core Web Vitals as a non-negotiable.

Quarry now owns their storefront instead of renting it from a dozen apps. Speed compounds — and so does everything downstream of it.
