Throughout my career, I have developed RESTful web services, concurrent applications, and integration solutions using Java, along with a wide range of related technologies. I’ve had the opportunity to witness Java's evolution as it continuously adapts, introducing features that enhance both its conciseness and usability, making it more accessible to developers. This evolution has been a central focus in my career as a trainer, where I have taught both children and experienced developers how to leverage Java to build both simple and complex applications.

Very helpful! I was having trouble using IntelliJ and Maven, but Vitaliy was able to instantly tell what my issues were and gave good guidance on what tools and features to use. I would recommend to anyone who wants to improve their Java skills.

Vitaliy was very knowledgeable in handling exceptions inside a java spring application and was able to walk me through multiple different ways in which I can handle them and the reasons I may pick one way over another.
