E-Commerce App and Windows Client

I am building a new e-commerce platform and need it delivered in two complementary pieces: the main customer-facing application (I’m open to either a mobile app or a web app, whatever you feel is the best fit) and a dedicated Windows client for in-house operations.

For the shopping experience, the essentials are straightforward: shoppers must be able to create and manage their own User accounts and complete purchases through a reliable, secure Payment gateway. Beyond that, I’m happy to discuss additional bells and whistles such as Product search later, but those two core capabilities have to be rock-solid from day one.

On the Windows side, I want a lightweight client that talks seamlessly to the same backend so staff can process orders, review customer details, and run quick updates without opening a browser. A cohesive codebase or shared API layer would be ideal.

If you have a proven track record shipping e-commerce solutions—especially those that bridge mobile/web front ends with desktop utilities—let’s talk through architecture, timelines, and any frameworks or tooling you recommend (React Native, Flutter, .NET, Electron, etc.). I’m ready to move quickly once we agree on a sensible plan and clear milestones.
