About
I'm a junior studying Human Centered Design & Engineering at the University of Washington. I'm interested in human-centered AI and building tools that people actually want to use — from iOS apps to full-stack platforms.
Outside of work, I shoot film photography and tinker with open-source projects, exploring the intersection of analog aesthetics and digital precision.
