Design Director · Product & Brand Designer

I'm currently Design Director at UPSIDER, leading a team of eight designers building a financial platform for challengers (acquired by Mizuho Financial Group in 2025), and Chief Design Officer at PartnerProp, where I design AIMO, an AI agent that acts as the product's primary interface.

In 2021 I co-founded Parsons & Systems, a design studio for startup product strategy, brand, and corporate identity.

Previously, I was a Senior Experience Architect at Adobe working on Acrobat, and Product Design Lead & Brand Management Director at BASE, designing Pay ID and BASE Card. I started out on Player!, a sports-viewing app by ookami, and doing design work in Los Angeles.
