About Kelly

I'm an American product designer based in the Netherlands.

I'm a versatile craft and people leader who can flex between designing hands-on and managing high-performing, AI-powered teams. From startups to scale-ups to big tech companies, I've shipped B2C and B2B products in a variety of industries and customer segments.

Today I help lead design and applied AI at Personio, a people platform for European SMEs. My team designs the Personio Assistant, Support AI, and Analytics & Reporting products.

Previously, I helped grow the global Product Design and UX Research function at WeTransfer through scale and eventual exit.

Earlier, I was the only designer at Smartify, an award-winning arts and culture startup behind the world's most downloaded museum app. It is now available in more than 700 museums worldwide.

I began my design career in the United States. At Messenger, I helped design the audio and video call experience for over a billion users, learning firsthand what it takes to design at the highest levels of scale. Earlier, at Tripadvisor, I started out as an intern and went on to design the travel site's native iPhone, Android, and Apple TV apps.

I studied media, journalism, and graphic design at Syracuse University's Newhouse School, one of the top public communications programs in the U.S.

In my life off screen, you can find me with my family in a village near Amsterdam, slowly but surely figuring out how to speak Dutch.

Thanks for visiting my little corner of the internet.
