Deep understanding of reactive programming: RxSwift for iOS, RxKotlin or Kotlin Flow for Android, Combine for modern iOS. Understanding streams, observables, operators, and reactive architectures. Benefits: elegant async handling, backpressure management, composable transformations. Drawbacks: learning curve, performance overhead in some cases. Building responsive, reactive mobile apps. When reactive programming helps and when traditional callbacks suffice. Hot vs. cold observables, subscription management, memory leaks in reactive code.
