About
I'm a design lead with 9 years of experience building and scaling consumer products, and I care most about the leverage good work leaves behind.
At IXL, I led the creation and long-term evolution of Quizzes, growing it into one of the company's most-adopted teacher tools. More recently, I oversaw design for Rosetta Stone's AI-powered chat-based language learning experience and drove the design system initiative to establish shared design standards across the organization.
I care about creating lasting leverage through products, systems, and teams that continue to deliver value long after launch.
Outside of work
You'll find me at the pottery wheel, on a run, in an art museum, or hunting for a new cafe with a hojicha latte.
Also: traveling, reading, pilates, cooking, baking (sometimes), learning a new language - currently French, photography (been loving my new Fujifilm)
