How I designed a 0→1 product that helps non-partisan elected officials govern with representative data
- 500+ elected officials onboarded within 45 days of soft launch

Just a designer learning how to code.
About
I do my best work when the problem is hard, and the path isn't obvious.
As a product design leader, I specialize in complex data architectures, zero-to-one products, and engineering-grade design systems. My superpower is bridging the gap between systems, code, and user intent. I have over a decade of experience turning high-friction enterprise complexity into intuitive digital products that drive growth.
When I'm not glued to my computer, I'm reading a physical book, exploring new restaurants, or attending to my 50+ plants.
