What I'm looking for

I'm open to Senior and Staff Product Design roles, remote or relocation.

At Hubees, I worked end-to-end on the B2C app and B2B products, from discovery through post-launch follow-up. As the only designer on the design-system project, I rebuilt the visual foundation around the brand’s new positioning and shaped components from the key user journeys.

At Hubees, I also introduced documentation and handoff processes for design deliverables that shortened time to production by 40%. I focused the launch on sign-up, check-in, and check-out, and shipped ahead of the original estimate.

At InvestAI, I founded the design team and built the design practice from zero. I owned the experience across four products and brought research findings and product metrics into roadmap discussions.

At Liv Up, I redesigned the web experience and built its design system before moving to the app team as its sole designer. For the shopping-list feature, I worked with a PM and data analyst on an A/B-tested experience that increased item variety by 20% among users with the feature and average order value by 13%.
