Have you used Kotlin outside of Android app development?

Yes, Kotlin is actively used not only for Android development but also in other areas. For example, Kotlin is used for writing server-side logic with frameworks such as Ktor or Spring Boot. Kotlin is also used for scripting and automation, thanks to its conciseness and JVM compatibility. Additionally, Kotlin/Native allows creating applications for iOS, macOS, and other platforms, while Kotlin Multiplatform helps write shared code for different operating systems.
