TIMEFRAME

Q1 2026

ROLE

Brand refresh, headless architecture, Shopify Storefront API integration, security audit.

WunderFit Labs — a veteran-owned supplement brand. Existing store was on a stock Shopify theme that was slow, generic, and hurting brand perception.

THE PROBLEM

Stock Shopify themes max out around 4-second mobile loads on supplement-heavy product detail pages, and the brand was losing mobile conversion. The store also needed a full identity refresh — new name (WunderFit Labs), new typographic system — that stock themes couldn't deliver.

THE APPROACH

  • Headless architecture: Next.js front-end talking to the Shopify Storefront API via a custom shopify-queries layer, so the site is static-fast but still syncs with Shopify inventory, pricing, and checkout.
  • Cart context and line-item management built client-side, with server-side fetches for catalog data.
  • Brand refresh: new identity system — League Spartan + serif pairing, proper label SVG work, tight typographic system.
  • Security pass before launch: HTML sanitization (isomorphic-dompurify) on product copy from the Shopify API, strict CSP on the Next layer, checkout still handled by Shopify's hardened flow.

STACK

  • Next.js
  • Shopify Storefront API (custom query layer)
  • isomorphic-dompurify
  • Tailwind
  • League Spartan
  • Resend
