The Challenge

What we needed to solve.

  • Off-the-shelf themes couldn't support merchandising features without bloating JS.
  • Brand teams needed editor-friendly sections without developer involvement for every change.
  • Mobile performance was non-negotiable for paid traffic ROI.
The Approach

How it was built.

01

Modular section library

Built a reusable library of sections — Shop The Look, Quick View, Bundles, advanced filtering — that brand teams can drop in via the theme editor.

02

CRO-first IA

Restructured PDP and collection templates around scannability, trust, and upsell placement informed by session recordings.

03

Performance budget

Enforced a JS budget per section with lazy hydration, deferred third-party scripts, and image strategy tuned for mobile.
