Hello,
I’m Roy, a product designer working across enterprise and consumer products, from shaping AI-powered retail experiences at Google and Creator experiences at TikTok Shop to driving Wallet growth at Coinbase and evolving core product experiences at MetaMask.
I'm building Rare Prompts, a home for AI inspiration where people share what they create so others can discover, learn, and build on their ideas.
Ate10 is a new way to rate and discover food in your city. Forget the ambiance, service, or long wait times. It's all about how good the food actually is.

I spent a year in Seoul taking photos of beautiful cafes I visited.

Helped shape the end-to-end trading experience, from how people discover and evaluate tokens to how they trade them.

Intuitive, lively, and scalable prediction markets.

Designed an ecosystem that helps creators discover, manage, and sell products to their audiences.
Previously, I worked on growth for Coinbase Wallet and spent six years at Google Cloud designing AI-powered retail experiences that helped e-commerce businesses improve search results and product recommendations. I also designed the first version of Model Cards, simple, structured summaries explaining how AI models were developed and evaluated.
