What experience do you have with Kotlin and how do you apply it in projects?

I am proficient in Kotlin at a level sufficient for developing Android applications, including the use of modern language features: coroutines for asynchronous programming, extension functions, data classes, sealed classes, and null safety.

In my projects, I use Kotlin for:

• Creating UI with Jetpack Compose or traditional XML.
• Implementing business logic using coroutines for convenient and efficient thread management.
• Utilizing libraries and frameworks written in Kotlin, which simplifies integration and improves code readability.

Example of using coroutines:

fun fetchData() {
    CoroutineScope(Dispatchers.IO).launch {
        val data = repository.getData()
        withContext(Dispatchers.Main) {
            updateUI(data)
        }
    }
}

Thus, Kotlin allows writing more concise, safe, and modern code for Android.
