How do you assess your knowledge and skills in multithreading and parallel programming?

In working with multithreading and parallel programming, I am familiar with the basic concepts: threads, tasks, synchronization, and data race issues. In Android, I use tools such as Handler, AsyncTask (deprecated, but useful for understanding), ExecutorService, as well as modern approaches with Kotlin Coroutines to simplify asynchronous code.

For example, with Kotlin Coroutines, you can easily run background tasks and update the UI:

GlobalScope.launch(Dispatchers.Main) {
    val data = withContext(Dispatchers.IO) { fetchData() }
    updateUI(data)
}

I understand the importance of proper synchronization and avoiding deadlocks to prevent ANR (Application Not Responding) in Android. I am also familiar with basic patterns such as Producer-Consumer and know how to use mechanisms like synchronized, volatile, and others to manage access to shared resources.
