About Katie

Clarity takes care.

Katie DeVoe

I’m a Staff Product Designer at Ninety, working across core product, design systems, and AI. I care about how a product behaves, how it’s built, and whether the details hold together.

My work spans complex SaaS products, mobile experiences, and the systems that connect them. I use working prototypes to make decisions tangible and partner closely with engineering to find simpler solutions.

Outside work, I photograph families and newborns and spend time with my husband and two daughters in Upstate New York.
