My Stuff


I am currently pursuing Master's degree in computer science at the University of Wrocław.


I used to teach classes in informatics and algorithms at the 14th High School in Wrocław and the 1st High School in Lubin. Now I focus on personal tutoring with gifted students.


Last summer I was a software developer intern at Google in Waterloo, Canada. I was also an intern at Facebook and I worked as a contractor for Codility and Codilime.

Competitive programming

I really like taking part in various programming contests. I am also a member of Jury of the Polish Olimpiad in Informatics and the Algorithmic Engagements contest.


Weaselcrow project has been suspended. It will be probably continued in the future.

Free time

When I finally have some spare time, I like travelling, swimming, hiking and playing some computer games.
