03 BEYOND THE STACK

Curiosity is a
working principle.

I’m drawn to problems where the pieces connect: software, data, people, and the systems around them. Science is a lasting source of inspiration, from the way matter behaves to the vast structures of the universe.

Music offers another kind of systems thinking. At the piano, patterns, timing, and creative instinct meet. Those same ideas shape how I approach engineering: listen closely, understand the structure, then make something that works beautifully.
