About.

I am a 17-year-old student driven by a passion for building great things. If an idea excites me, I am committed to bringing it to life.

My curiosity for how things work has been a lifelong journey. Realizing I could not only understand but also create things myself—and that design alone could evoke emotion—was a turning point.

When I'm not building, I enjoy connecting with new people, exploring philosophy, and engaging with the crypto space. I believe in balancing hard work with time for enjoyment and reflection.
