Hi, I am Kelsey (Kexin Sha).

As a product designer, my work spans complex desktop software, data-heavy web apps, and AI mobile products.

I care about education, tools people can actually understand and use, and the quiet craft behind them. An industrial design foundation gives me a constraints-first, systems-thinking way of working; and HCI research keeps it grounded in real user behaviors.

Outside of work, I’m drawn to narrative deduction games, sci-fi, music, birding, and hiking. I like following clues and uncovering the logic beneath complex systems.

The best design starts with a real question, so let’s ask one!
