Develop tasks relevant to your expertise: cross-platform applications using TypeScript, JavaScript, or Dart; iOS applications using Swift; or Android applications using Kotlin

Cross-platform: TypeScript or JavaScript with React Native, or Dart with Flutter
iOS: Swift with SwiftUI or UIKit
Android: Kotlin with Jetpack Compose or the Android View system
Deep understanding of mobile application architecture, state management, asynchronous programming, and application lifecycle
Proven ability to debug complex mobile applications, resolve bugs, and deliver effective performance improvements
