Tell me about the technical tasks you had to solve in practice.

In practice, I have had to solve various technical tasks, such as:

• Optimizing Java application performance through profiling and bottleneck elimination.
• Implementing REST API using Spring Boot, including error handling and data validation.
• Integrating with external services via HTTP and JMS.
• Writing unit tests and integration tests to ensure code quality.
• Solving multithreading issues, such as synchronizing access to shared resources.

An example of a synchronization task solution:

public class Counter {
    private int count = 0;

    public synchronized void increment() {
        count++;
    }

    public synchronized int getCount() {
        return count;
    }
}

This approach prevents race conditions during parallel access.
