Product designer for health tech,
nonprofits and AI

I design products from the first round of user research through launch, working closely with engineering and product teams. On small teams I often run the project too, so timelines and handoffs stay on track.

Green Chef: Onboarding Redesign

New subscribers were cancelling before their first order. My first tutorial design failed usability testing, so I switched to a carousel, which shipped and became the model for later onboarding.

A bit about me

Psychology background Research-first Research through launch AI-assisted Boulder, CO

I'm a product designer with a background in psychology and user research. I like to talk with users before I design anything, and I stay on a project through handoff and launch, keeping clients and engineers in the loop. I use AI throughout, mostly for research synthesis and for checking designs.

How I work

User Research

I pick the method based on what the team needs to decide, whether that's interviews, a survey, usability testing, or a card sort. Then I share the findings in a form product and engineering can act on.

UX & Interaction Design

Information architecture, user flows, wireframes, and prototypes. I try to make complex systems easy to move through, and I design to WCAG standards so interfaces work across devices.

AI-Assisted Workflow

I use Claude for research, project planning, and content development, and Claude Code to build and refine designs. Most of my recent freelance work has been with AI startups, where I manage projects and design AI products.

Project & Client Leadership

Scoping work, running timelines, and translating between what clients ask for and what the team builds. I have led projects solo and inside cross-functional teams.
