What experience and competencies can you demonstrate in your professional activity?

In my professional activities, I can demonstrate the following competencies:

• Knowledge and experience in Java development, including working with collections, streams, and exception handling.
• Experience with multithreading and synchronization, using atomic operations and locks.
• Ability to write clean, maintainable code using OOP principles.
• Familiarity with build tools (Maven, Gradle) and version control systems (Git).
• Experience working with databases and writing SQL queries.
• Skills in debugging and testing code, including writing unit tests.

Example: in one of my projects, I implemented a multithreaded service that processed requests in parallel using ExecutorService, and ensured correct operation with shared resources through atomic variables and synchronization.
