    Russia - Last active: 1 month ago - Tests: 2 - Portfolio: 1

    I'm a "general purpose" java developer with some experience in enterprise development (are my responsibilities at my previous job). I always try to develop software that suits customers (both functionality/deadlines) and is easy to maintain later, based on modern technologies(frameworks/libraries): apache-commons, google-guava, EE, Spring, Velocity, PDFBox, Thymeleaf and others where they really help. The result, unless otherwise specified, will be shipped as executables/ready-to-use binaries and sources files. Thank you!
