I am quite active in sports programming in Poland, earlier as contestant, now as problem creator and sometimes member of organizing/technical commitees or jury.
I created Solve System 3, an online judge that helps young people to learn algorithms and programming.
I am member of Main Commitee of Polish Junior Olympiad in Informatics. If you have some interesting problem ideas that you would like to submit for the competition, please write an e-mail to me (remember to encrypt the problem, my key is available above).
I really like cars.
