Situation

The brand already had Shopify in place and wanted a dedicated mobile experience without rebuilding commerce infrastructure from scratch.

Build

I built a React Native / Expo app that owns the mobile browsing and cart experience while Shopify remains the source of truth for catalog, checkout, payments, orders, and accounts.

Result

The app is functional and ready for the business to launch when priorities align. It shows mobile commerce and Shopify-connected app delivery.

Key decisions

  • Kept checkout and payments on Shopify to reduce sensitive handling inside the app.
  • Used a backend boundary for privileged account operations instead of exposing admin credentials.
  • Designed the app around bilingual mobile UX and region-aware commerce configuration.
  • Integrated with the existing commerce backend rather than duplicating product and order systems.
