About Me

I pronounce it 'Cull-um' but I'm always open to new interpretations.

I'm a product designer based in New York City. Over the past decade, I've worked across the full spectrum of digital product — designing enterprise systems at IBM, building award-winning e-commerce experiences at Astound, and shaping the stories, feed, and reels creation tools used by billions of people at the world's largest social media platform.

I'm skilled at solving complex user problems and delivering results, whether that's moving fast as part of a small team or working with large complex systems and teams. I make good stuff.

When I'm not designing, my passion is analog film photography, particularly street photography. I love to wander around cities and capture unique moments between people and places.
