Matterport: Figma for Reality Capture
0→1 Design System
Prototyping Culture & Alignment
Product Vision & North Star
Takeaway
At Matterport, I’m leading design for Composer, our first new product surface in five years and a 3D design tool for architects, engineers, and builders. In less than 6 months, our team took it from sketches on a whiteboard to a revenue-generating product that has expanded our sales opportunities and addressed years of customer requests.
Matterport’s $1.6 billion acquisition by CoStar Group in 2025 signaled strong confidence in the role of B2B products like Composer in shaping the company’s next chapter.
Design Outcomes
- 30%faster strategic alignment with execs
- 2×increase in cross-functional participation
- 40%faster design-to-ship cadence

Dear Uses AI for Thoughtful Connection
Quiet Craft of AI & UX
Product-led Branding
Product Vision & GTM
Takeaway
I’m building Dear, an iOS app that uses AI to make staying connected with the people you love feel natural and easy. Reaching out shouldn’t feel like another task on your to‑do list.
Dear supports you without taking over. It learns from your voice, your tone, and the way you already write, so the messages still feel like you. In our private beta, eight out of ten users said their messages felt authentic and personal, and they found themselves reaching out more often to friends and family than they did before.
Outcomes
- 80%beta users say messages feel authentic
- ↑ Increasedoutreach to friends & family compared to before

Rebrand to Revenue in 5 Months
Founding Onboarding & PLG
First Design System
Takeaway
In just five months, I helped a YC and NEO-backed company find its voice. Partnering with their CEO, COO, CTO, and Head of Product, I led a complete rebrand, built their first design system, and designed onboarding that became the foundation for their product-led growth motion. The company went on to reach #1 on Product Hunt twice, earning Product of the Day both times, and driving the kind of momentum that proved we had built something built to last.
Outcomes
- 2×Product of the Day on Product Hunt
- 5 morebrand to revenue + PLG foundations
- 1stdesign system shipped

Ex-Agency. Ex-Founder. Forever Curious.
I'm a product designer with 10+ years of experience and a background at design agencies, where I built consumer products for fortune-tier companies like Samsung, Intel, and AT&T.
I've founded two companies, one backed by Techstars and one as a nonprofit, and later became the first designer at startups from Series A to growth stage. I love to work side by side with leadership to launch 0–1 products, shape brands, and hire early design teams.
Today I bring that founder's perspective into larger organizations, building with high craft and shipping quickly by creating strong, trusted relationships across teams.
When I'm off the clock, I love exploring San Francisco with my family, volunteering with my nonprofit, and making things—objects and experiences—that fill life with unexpected joy.
Service & Volunteering
Supporting Babies in the Hospital
I founded Foxbox after our four-month-old was diagnosed with leukemia. Today, the nonprofit supports babies and families through long hospital stays, reaching 130+ families across five children's hospitals in the U.S.

Learning Hard Things
I've been learning to ride my Honda MSX125. It's a compact bike that's teaching me a lot about control, grit, and how to get back up after you fall.
