Computer science student at so called Matfyzcs, officially Faculty of Mathematics and Physics, Charles University in Prague (Wikipedia). Webmaster of The Grammar School of Kladno since about when in 3rd year of its 8-year study program (14 years old), with very few time to maintain its website lately.
Web, programming languages, teaching, music (guitar, largely genre-neutral), martial arts (kendo, judo), … and many other.
I am very precise in everything I do. I seldom regret returning to an old piece of code I wrote to fix a bug or perform other maintenance, because I write well-structured and usefully-commented code with sane naming convention.
