Do you have practical experience in development using Kotlin Multiplatform for creating cross-platform applications?

Kotlin Multiplatform allows writing shared code that runs on different platforms — Android, iOS, Web, and others. Practical experience includes setting up a common module, writing business logic in Kotlin, and integrating with platform APIs through expect/actual mechanisms. For example, you can implement a shared data layer and use it in both Android and iOS applications, which significantly reduces code duplication and speeds up development.
