About Daniel Długosz

During few years of my carrier in Warsaw I've managed to develop very much in psychological and management area along with IT. I've faced a lot of deadline and tough decision making situations which made me who I am right now. I'm taking experience of my actions- good or bad, and not making the bad decisions twice. I know how to work in different cultural areas and if it comes to IT systems and technologies always opened for new knowledge. I'm willing to work hard and I can give my word that I'll always do my best to reach the goal.
