Restaurant Ordering App Clone

I need an exact replica of the ordering experience found in the hamburguer site built with Lovable App (see it live at https://www.bravusburguerbe.com/menu). Every screen, flow, and back-end function should remain intact—menu browsing, modifiers, cart, checkout, loyalty logic, push notifications, and the admin controls I already use on the current system. The platform coverage: I want the finished product running natively on iOS , Android an windows computer. Feel free to use a cross-platform stack such as Flutter, React Native, or any technology you’re comfortable with as long as performance and UI parity match the original. The visual style, colors, typography, and layout all stay the same; no redesign work is required beyond making sure everything looks pixel-perfect on the target devices. Because this is a straight clone, the project will be judged on perfect functional parity. To make that measurable, here are the acceptance points I will test before sign-off: • All menu items, categories, and option sets display exactly as on the current app and pull live data from my existing CMS. • Add-to-cart logic, pricing rules, and discount handling behave identically. • Checkout integrates with the same payment gateway and produces the same order confirmations. • Push notifications, order status updates, and the admin dashboard work without regression. • The apps build cleanly in Xcode and Android Studio and pass store submission checks. Source code, build instructions, and any configuration files are part of the final hand-over. If you’ve done restaurant or e-commerce clones before, let me know; speed and fidelity are the priorities here.
