About

Designing for the moment someone gets stuck.

My work is rooted in the belief that government and civic services should be held to the same standard as the best consumer products. Access to benefits, healthcare, and public infrastructure shouldn't depend on someone's patience for a broken interface.

I'm a Staff Product Designer at Login.gov, the federal government's single sign-on service used by over 150 million Americans to access benefits and services. Before moving into civic tech, I was the founding designer at Flare, taking the product from 0 to 1 and scaling it to 500K+ monthly users across 500+ colleges, and a Product Designer on IBM Watson Assistant, where I owned the overhaul of the chatbot-building experience for non-technical users. I also worked with HUSH Studios on experiential design for clients including Uber.

I hold a BFA in Graphic Design with Honors from the Rhode Island School of Design, and I'm based in Brooklyn, NY.
