Burger Craft Bot is a

Burger Craft Bot is a Telegram Mini App that lets restaurant guests order craft burgers, combo meals, snacks, and drinks directly from their table—without downloading another application, registering, or waiting for a paper menu. Users simply scan a QR code and begin ordering in Telegram. Our team built an intuitive product catalog and meal customizer that supports visual topping selection, flexible fulfillment options, automatic table identification, and direct waiter calls. The ordering flow integrates Apple Pay, Google Pay, card payments, and cash requests through a waiter. We implemented transaction idempotency for order placement and payment gateway calls, preventing duplicate receipts and double charges during repeated clicks or unstable mobile connectivity. The platform serves 13,000+ users, achieved 97% customer satisfaction, supports multilingual operation, and provides complete data and access security.
