03 / Background

BeginningsNo.3

Born in San Francisco, I moved around the US and grew up in the Bay Area. Now I live in the Basque Country. Change has always been part of me, and one thing holds true: life will shape you, and you must shape it back.

It started with civil engineering and art foundation classes. Design was not a path I knew, and it felt invisible the way it does when done well. Curiosity and fellow artists and designers helped unveil a more deliberate one: image making, typography, photography, animation, building websites, and finding ways to bring those skills together.

Luck grows with the surface area of people you know. I meet people with the intent of making earnest connections.
