Challenge
Upper optimizes multi-stop routes for delivery drivers — up to 500 stops per route. The main delivery challenge was to give users real-time operational data that remains usable under time pressure and unstable connectivity, while keeping Import, Optimize, and Dispatch consistent across the complete journey. We framed the engagement around the smallest production-worthy flow first, then expanded the scope without weakening the underlying component and data model.

How we built it
We started with the navigation model, reusable screen primitives, and the data contracts behind the most important user journey. From there we delivered Import, Optimize, and Dispatch in vertical slices, so every milestone included a usable interface, live data, validation, and error handling. Realtime updates and offline recovery were designed together because mobile connectivity could not be assumed. The application foundation centred on React Native, Expo SDK 54, Expo Router, and TypeScript, followed by device testing and release hardening for iOS and Android.
03
Delivery
The delivered scope brought Import, Optimize, Dispatch, and Navigate into one coherent cross-platform mobile release. Live updates, recovery states, and operational feedback are part of the core flow rather than late-stage patches. For Upper, the practical result is a product that communicates its value quickly while giving the team a maintainable base for continued delivery in logistics & field ops.
