Kotlin Multiplatform (KMP) lets you share code across Android and backend modules while maintaining platform-specific implementations. Structure your project with shared, Android, and backend modules in Gradle, then use expect/actual declarations for platform differences.

Coroutines provide lightweight, suspension-based concurrency for async tasks. Use suspend functions, launch, and async builders to handle asynchronous operations cleanly without callbacks, making code more readable and maintainable.

Yes, Kotlin integrates seamlessly with both Spring Boot and Ktor frameworks. Kotlin's null safety and extension functions reduce boilerplate in backend services while maintaining full Java interoperability.

Kotest and MockK are standard testing libraries for Kotlin. Kotest provides coroutine-aware test runners and assertions, while MockK handles mocking with Kotlin syntax, making unit and integration tests more concise.

Kotlin eliminates null pointer exceptions through null safety, reduces boilerplate with extension functions and data classes, and integrates with Jetpack Compose for modern declarative UI, improving developer productivity and app reliability.

Gradle Kotlin DSL provides type-safe, IDE-aware dependency management over traditional Groovy scripts. It's the modern approach for Kotlin projects, offering better autocomplete and error detection in build configurations.
