Who am I?

My name is Tomasz Watorowski, but you probably know that by now. I've graduated from Poznan University of Technology where I've got my M. Sc Eng degree in Computer Science. Since then I've worked on many different projects some of which have reached the stage of mass production. So, to keep the long story short here is a list of my skills.
