Do you have skills in multithreading in programming?

Yes, I have worked with multithreading in Java, using classes from the java.util.concurrent package, such as ExecutorService for managing thread pools.

For example, in one of my projects, I implemented parallel processing of a large volume of data by dividing tasks among multiple threads to improve performance:

ExecutorService executor = Executors.newFixedThreadPool(4);

for (Runnable task : tasks) {
    executor.submit(task);
}

executor.shutdown();
executor.awaitTermination(1, TimeUnit.HOURS);

I am also familiar with thread synchronization using the synchronized keyword and Lock classes to prevent race conditions and ensure proper access to shared resources.
