Autobiography
I'm a high school junior from Subotica (Serbia) who's been coding since 9 and I love turning small ideas into tools people actually use. I'm a leader by nature when I know the topic – organizing youth events, mentoring peers and collaborating with schools all because helping others navigate education motivates me as much as building. Most days I split time between web/mobile work and competitive programming, then reset by doing sports or hanging out with friends. I've earned some awards along the way, but I care more about my momentum: to learn fast, ship often and share what I know. I'm happiest when something I build removes friction for someone else and sparks them to try building too.

Vision for the future

My goal isn't to be successful — my goal is to help others be successful. I believe in the 98/2 rule: 98% of people do what everyone else does, while only 2% try to make a real difference. I strive to be in that 2%.

I want to be a mentor who doesn't just share knowledge, but inspires, encourages and helps young people see the bigger picture. The activities of EduCompass Association are just the beginning.

Long-term, my goal is to be a driver of innovation at the intersection of technology and education.

(100% + 1%)365 = 37.78 ≫ 1 = (100%)365
Get 1% better every day. That's enough.
