CASE STUDY · 2025

A fashion store that loads fast and converts better.

Replaced a slow, inflexible CMS with a purpose-built Next.js storefront. Custom content management, aggressive caching, and a checkout flow that doesn't get in the way.

THE PROBLEM

A CMS that punished everyone who touched it.

The old site ran on a platform the client had outgrown. Adding a product required touching three separate screens. The homepage was a template the client couldn't edit without breaking the layout. Sales required manual discount codes entered into a spreadsheet.

The site was also slow — 4.8s LCP on mobile — because every page load fetched live from an underpowered shared server with no CDN.

APPROACH

Static where possible, dynamic only where needed.

Product pages, collection pages, and editorial content are all statically generated at build time and served from Vercel's edge network. Cart, checkout, and account pages are dynamic. This split cuts infrastructure cost to near-zero while handling traffic spikes during sales without breaking a sweat.
