My Interest

First of all I love music, electro swing and chillhop music are my favorites. Without fresh portion of swing and chillhop everyday I can't feel good enough. Love spending time with smart people discussing the life and implementing new concepts into live. I spend quite a lot of time in traveling and photography, these keeps me fresh for working environment. I also spend some time volunteering and doing non-profit projects.
