For many years, my main research subject has been eye movement research. Clicking the link you can find a short description of this subject with some references to our papers.
My other job involves teaching and training people to become good software developers, both at the Silesian University of Technology and during commercial trainings. I have prepared and organized almost 200 courses; you can check the details here.
I have practical experience with many tools (i.e., sold projects and happy customers). Moreover, I am ready to learn new ones if I have to. A previous version of this page also contained a list of my projects, but it isn't available anymore because of different NDA-related problems. I may only write that I worked as a freelancer for many companies, including 2Si, ABG, ComArch, Computerland, ESAB, OandS, Pokomtel, ZETO, and others. If you are interested in any topic but cannot find it on the webpage, please contact me!
