I've spent the last few years building interfaces at a dental AI startup — making complex clinical workflows feel natural. But what I really care about is the moment a person using something I built pauses, notices a detail, and feels like someone thought about them.

I studied psychology before I wrote my first line of code. I still think about interfaces the same way I think about a conversation — there should be rhythm, there should be surprise, and there should be space to breathe.
