Stack

Next.js, React, SCSS

Collaboration

Direct B2B, end-to-end frontend

Starting point

The store needed a modern frontend with a full purchase flow and better mobile responsiveness. Previous solutions created checkout friction and slower loading on key product pages.

Store implementation

  • Built key product and category pages with a mobile-first UX focus.
  • Implemented checkout, payment integrations, and shipping methods.

Performance

  • Code splitting and lazy loading for heavier modules.
  • Asset and rendering path optimization on mobile.

Outcome

A stable store with a complete purchase flow, improved responsiveness, and faster perceived loading on mobile — ready for further growth without a full rebuild.
