Interests

In my free time, I enjoy staying fit by going to the gym regularly. I also practice paintball at least once a month, which gives me an adrenaline rush. I'm passionate about sports, especially basketball and baseball.

I also love exploring new places. Currently, I’m traveling around the country, discovering different destinations, with the goal of visiting various countries in the near future to broaden my horizons.

One of my short-term plans is to visit Denver, Colorado, to go skiing with my wife. We’re aiming for January 2026, to enjoy the stunning mountains of Aspen.
