Hi, I'm Ryan. I design products that make complex things feel simple.

I start every design by asking the right questions and mapping how the whole system fits together. Then I build quick AI prototypes to test ideas early, before the team commits.

At PayPayJapan's largest mobile payment app in Tokyo, I make paying and managing money easy for 65M+ users, even when the rules behind it are not. Before that, I worked on growth and retention at CarousellMarketplace app across Southeast Asia and Taiwan in Taiwan and Singapore.

Outside work, I mentor designers at AAPDEducation platform for product builders in Taiwan and build small tools with code and AI.
