What is your experience with the Kotlin language?

I have experience developing with Kotlin within Android applications. I used Kotlin to create UI with Jetpack Compose and traditional XML, worked with coroutines for asynchronous tasks, and also applied Kotlin DSL for configuring Gradle builds.

Example of using coroutines in Kotlin:

import kotlinx.coroutines.*

fun main() = runBlocking {
    launch {
        delay(1000L)
        println("Hello from coroutine!")
    }
    println("Hello from main")
}

I am also familiar with null-safety features and language extensions, which improve code quality and readability.
