Slice's consumer app is an online ordering marketplace for local pizzerias, with order tracking, order history, payments, and rewards.

I worked on the order-tracking experience and integration with the Owners app, alongside improvements to stability and maintainability, in an app with millions of monthly sessions.

My reliability work emphasizes finding defects before release. When issues surface, I assess whether they affect the core ordering flow and what percentage of users is affected. Most features launch behind feature flags, and every flag can be disabled remotely without waiting for an App Store update.

The established codebase combines UIKit and SwiftUI, primarily using MVVM with coordinators. Its technologies include RxSwift, Combine, Swift Concurrency, and SnapKit, with Quick and Nimble used for testing.
