Hi, I am Arek. I am proud graduate from Military University of Technology in Warsaw, Poland. I have successfully obtained there my PhD degree in cryptology, but I have to admit it was done more as an additional activity, at that time. Professionally, I am involved in data processing from the very beginning of my carrer. Currently I am living and working in Zurich Metropolitan Area. Introvert, with no fascinating hobbies.On this website I want to share my latest activities, done mostly in order to learn something new. Currently, it is not yet fully adjusted to mobile devices :(
