“I am an IT generalist with a background in mathematics, currently working as a freelance coder. I always get drawn to the most tricky puzzles, also outside of the IT realm, for example Go and Sudoku.

Still I am not sure yet, but it seems the only thing in life that really matters is music. My favourite range of music is from Mozart to Rachmaninov, but I like almost all music. And I do play the piano a little bit, too.”
