Product Engineer

Timothy Yang

I design and ship end-to-end products.

A product engineer who owns the whole surface — React, TypeScript, and React Native on the front, the API and data model behind it. I've shipped a startup's mobile product end to end, and seven products solo as my own studio, six of them live on the App Store.
