Blayn Mobile Order

Browser-based QR table ordering for one of Japan's largest POS providers.

In short

A browser-based QR ordering system that lets restaurant customers order from their table with no app install, integrated with Blayn's POS backend.

The problem

Restaurants on Blayn's POS needed table-side ordering that works instantly on any phone. Asking customers to download an app at the table kills adoption.

My approach

Built the ordering flow as a browser app in React and TypeScript, launched from a QR code at the table.
Integrated REST APIs against Blayn's POS backend, with Redux Saga coordinating the async order flow.
Kept the experience consistent across the browsers and devices customers actually bring to a restaurant.

Outcome

No-install table ordering running against the production POS, usable on whatever phone the customer pulls out.
