Hobbies
Outside of work, I like to keep active — I train regularly at the gym, play five-a-side football with friends, and practice MMA, which keeps me grounded and focused. I'm also a bit of a curious mind: I enjoy listening to podcasts (everything from science and tech to human behavior), and I like watching scientific and thought-provoking videos on YouTube when I'm relaxing.
To unwind, I read manga, binge the occasional mystery or thriller series, and play board games that involve strategy and negotiation — I'm always up for a challenge. I also have a Rottweiler named Koby who keeps me on my toes and is very much part of the routine. I enjoy learning new things, whether it's through a podcast, a book, or just conversations with interesting people.
