Do you have experience working with Kotlin?

Yes, I have experience working with Kotlin. This language is excellent for development on JVM, Android applications, and server-side applications due to its concise syntax, support for functional programming, and full compatibility with Java.

In projects, I used Kotlin for:

• Creating Android applications using coroutines for asynchronous programming.
• Developing backend services with frameworks such as Ktor or Spring Boot.
• Writing unit and integration tests using Kotlin Test and JUnit.

An example of simple Kotlin code with a coroutine:

import kotlinx.coroutines.*

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

This experience allows me to effectively utilize Kotlin's capabilities to enhance productivity and code quality.
