About

Whether I'm designing AI-powered tools for investigators or building personal projects from scratch, I'm motivated by understanding users, solving meaningful problems, and crafting experiences that feel intuitive and reliable.

Outside of design, you'll usually find me at aerial classes, hiking, reading, or working on my next side project.
