Beyond the code

Running

I'm a self-proclaimed professional mediocre marathon runner. I love the challenge of long-distance running and often do races, sometimes with friends just for fun.

Nature & Mountains

Mountain and nature lover. I enjoy hiking and discovering new landscapes wherever I go. There's nothing like fresh air and a great view to clear your mind.

Music

Music is a constant companion - whether I'm coding, running, or just relaxing. I enjoy discovering new genres and artists.
