I am looking for an experienced Flutter developer to create a multi-vendor QR code ordering app for a new enterprise. The app should enable vendors to manage their offerings and customers to place orders seamlessly using QR codes. The project scope includes building a functional, user-friendly interface that supports multiple vendors, integrates payment gateways, and ensures smooth order management. I value clean, well-documented code that adheres to best practices. Backend should be on Laravel, php or node js. Admin panel, Vendor panel and customer panel will be. Please include examples of your past work related to Flutter development in your application. The project deadline is within a month, so timely delivery is essential.
