I do web/mobile design/development and offline/print design. My primary skils are web design, HTML, CSS, jQuery and CSM knowledge followed by mobile web design, offline design, photography and competition analysis. You can see all of them combined in my portfolio.
This is the question that I asked myself a while ago and got the answer in no time. I do this because I would like to change some things, help someone to present himself/his company in the world wide web and offline. This is what I do best and what I want to do in the future - till I grow old :)
