  • Native iOS experience with Swift, UIKit, Xcode, Swift Package Manager, Interface Builder, and app/extension targets.

  • Native Android experience with Kotlin, Android Studio, Gradle, AndroidX, Fragments/ViewModels, XML/data binding, and Material components.

  • Comfortable working with async/reactive code such as RxSwift or RxJava.
