Education

I earned a master's degree in Computer Science from the University of Wrocław. Additionally, I obtained a bachelor's degree in Joint Studies in Computer Science and Mathematics from the same university.

Sports programming

Sports programming is a mind sport focused on solving algorithmic puzzles. I am an international grandmaster and I am a top contributor on Codeforces - one of the biggest platforms with programming contests. I also won a bronze medal in Polish Olympiad in Informatics and Central European Regional Contest. I am the chair of the jury in Polish Junior Olympiad in Informatics and Algorithmic Engagements - the biggest open programming competition in Poland. I am also a problemsetter in Google Kick Start.

Teaching

I used to teach informatics in 14th High School in Wrocław and 1st High School in Lubin, my home town, but now I focus more on personal tutoring with gifted students. My students have great achievements in Polish Olympiad in Informatics (7 gold, 5 silver, and 10 bronze medals) and International Olympiad in Informatics (5 gold, 1 silver, and 1 bronze medal).

Traveling

In my free time, I love visiting new places. I have visited 50+ countries on 6 continents.
