Kotlin Multiplatform (KMP) enables shared business logic across platforms through a common module with expect/actual declarations. This Skill provides architecture patterns and structured concurrency patterns using coroutines to handle async operations consistently across iOS, Android, backend, and web targets.

Structured concurrency with Kotlin coroutines provides type-safe, cancellable async handling across platforms. This Skill covers coroutine patterns, Flow and StateFlow for reactive streams, and concurrency best practices to ensure safe, performant multiplatform applications.

Compose Multiplatform enables declarative, type-safe UI code shared across Android, iOS, web, and desktop from a single codebase. This Skill integrates Compose patterns with KMP architecture and covers testing with Kotest and MockK.

Kotlin 2.0 enforces null safety and supports type-safe domain models via sealed classes and DSLs. This Skill provides setup patterns for common modules, platform-specific targets, and extension functions to structure enterprise KMP applications.

Security in KMP requires platform-specific handling for sensitive operations while maintaining shared business logic. This Skill addresses security patterns, performance optimization, and memory considerations across Kotlin 2.0 multiplatform targets.

Kotest and MockK support shared test logic across KMP targets with platform-specific implementations where needed. This Skill covers multiplatform testing patterns to validate coroutines, domain models, and UI logic consistently.
