Products where people connect, designed and shipped.
I’m Sang Han, a principal product designer for social and communication products. I led design on Roblox Connect, shipped to four platforms at once, and was the founding designer at an AI startup. I work as a design team of one, or as part of yours.

Bring me in for a few weeks or a few quarters. I work in your tools, I’m productive in the first week, and I stay hands-on from the first sketch to the shipped detail.
