01About

I live where design meets engineering. That means I can take an idea from a sketch to a tested, accessible, production interface without losing anything in translation.

Right now I'm the UI/UX developer at Ask Sage, a BigBear.ai company, shaping how government and enterprise teams work with generative AI. Before that, I led the UI/UX department at ERA Solutions. Outside the day job, I run a small studio building custom websites and products. I'm also a proud Army National Guard veteran.
