Complex products, made simple.
I’m Matthew Christian, a Senior Product Designer with 8+ years of crafting delightful experiences that help businesses connect better with their customers.
Selected work
BTC Yield+
A new way for BTC holders to earn yield without trading derivatives. I designed the whole lifecycle, from first visit to subscribe, monitor and redeem, so people could understand the product before committing real capital.
Used by 3,900+ active users on average, with 112 daily active traders and $13M+ in average monthly trading volume.
Read the case study
The landing page before and after testing with 16 internal users. It scrolls as you move down; drag to compare.
Advanced RFQ
Traders building large, multi-leg trades had to jump between a builder, a quote board and a separate product on one tab bar. I brought building, monitoring and executing onto a single screen.
EatWhere?
A multiplayer, no-login web app that settles where a group should eat. Everyone votes from their own phone, then the app reveals a winner and real restaurants nearby. Designed and coded end to end with Claude, no engineers.
“I spent more time designing that 3-second screen than anything else in the product.”
