Anton P.

I am a Java developer with 3 years in the back-end field of using design patterns, UML, back-end engineering principles, and concepts. I design and implement projects from scratch with up-to-date technologies. One of my key abilities is the ability to learn really quickly while being open to new opportunities, that lead to the delivery of the best solutions.
