Web & Digital Platforms
Three ageing storefronts sharing one overloaded template were rebuilt as a headless front end on a shared component library, cutting page load times and ending the annual Black Friday panic.
The situation
Product pages took over six seconds to render on mobile, and mobile was 71% of traffic.
Three brands shared one heavily patched theme, so a fix for one frequently broke another.
Peak campaign traffic required over-provisioned hosting all year to survive two days of demand.
Merchandisers could not change page layouts without a developer release.
Our approach
We established Core Web Vitals and conversion baselines per brand and device, so the value of each change could be demonstrated rather than asserted.
A Next.js front end consumes the commerce platform through its API, letting us rebuild the customer experience without migrating orders, customers, or payment configuration.
Shared components carry brand-specific design tokens, so each storefront looks distinct while a single fix applies everywhere.
Layouts became composable blocks in the CMS with preview, removing developer involvement from routine campaign changes.
The outcome
Largest Contentful Paint on mobile product pages fell from 6.2s to 1.4s, and mobile conversion improved across all three brands in the first full quarter. Static rendering and edge caching cut hosting spend despite handling a heavier peak than the previous year, which passed without incident.
