I began programming when I was about 8 years old. Started from small - wrote my first programs using long-forgotten language G-BASIC, later it was QuickBasic, and then Delphi with all charms of visual programming. Year by year, time passed, technologies were changing (there was a time when I was writing in C++, C#, Ruby, Scala, Haskell, PHP, and more and more Java), and this isn't all. Today I'm working with a lot of tools for Big Data processing (and taking a part in work on a couple of them).
