Sajiin | QR Menu & Restaurant Ordering Platform

Sajiin: connecting a table QR menu to the restaurant team behind the order.

The problem Customers and staff need a shared view of menu choices, item notes, payment status, and kitchen progress.

My solution I built a browser-based restaurant ordering platform with table-specific QR links and an operational dashboard.

Key features • QR menus, categories, carts, and item notes • Payment status and customer order updates • Kitchen order stages and waiter requests • Menu/table management and multi-branch workflows • Sales reporting and staff permissions

Engineering notes Prices are recalculated on the server, payment webhooks are verified, and access is scoped by role and branch. Polling keeps the views updated; demo payments use Midtrans Sandbox.
