I’ve proudly helped to build & ship applications used by 200 million people.

I’m good at finding simple patterns in complex systems, as well as spotting 2-pixel imperfections. I enjoy working with people from whom I can learn. I’ve led teams, have a master’s degree in psychology, and know how to import React and useState.

Please don’t tell anyone, but I’ve never actually used Post-it Notes for work.

Instead, I go for Sketch, Figma, Framer, and Javascript. User interfaces are interactive so I design them that way. My favorite animation curve is 0.3s ease-out.
