Slice Driver is the delivery app used by drivers on the Slice marketplace, part of the Slice Register ecosystem.

It helps drivers review order contents, launch navigation with one tap, and keep delivery progress updated in real time.

The app is built natively in Swift with UIKit and integrates real-time delivery state handling, order verification flows, and location-based navigation support for drivers on the road.

The tech stack is UIKit with MVVM architecture.

I did maintenance and bug fixes on the app, while improving reliability and maintainability of key delivery flows, and ensuring the ordering lifecycle is easy to complete under difficult networking conditions.
