A cross-platform mobile commerce app with product catalogs, secure checkout, order tracking, and push notification engagement flows.

The app was designed mobile-first around the browsing and purchase journeys customers care about most. A single shared codebase across iOS and Android keeps delivery fast, while platform-specific layers handle native authentication, secure storage, and push notifications properly.

Checkout was the most sensitive part of the build. It uses hosted payment flows so raw card data never touches the app or server, with idempotency keys so a retried tap cannot double-charge. Server-side totals prevent client-side price tampering.

Offline-first catalog handling lets shoppers browse and compare products even on poor connectivity, syncing changes when the connection returns. Deep linking and personalized push notifications tie the app back into the broader marketing funnel without becoming intrusive.
