I make complex products feel simple
I'm Karl Wu, a product designer who codes. I turn complicated products into experiences that feel effortless, considered down to the last detail.

About me
I design and code the parts of a product people use: how a flow moves, what a button says, how fast someone gets to what they came for. Most of that has been at Fiserv and Clover; I started on the product side, as a PM intern at TikTok.
At Clover I design the AI merchants use every day. An assistant they can talk to, an agent that takes the next step for them. The part I care about most is the moment a suggestion stops feeling like a guess, when someone can see where it came from and act on it.
Away from the screen, I'm usually on a bike, behind a camera, or taking apart something well-made to see what makes it work.
