Hello, I'm Dennis
I like to build things on the Internet. I'm based in London and am from the Bay Area, but have lived in a few different places, from Boston to Shanghai to Taiwan to now London.
Currently, I'm exploring new projects in consumer AI. Previously, I worked as a Product Manager at Twitter, Facebook/Meta, and Instagram.
In my free time, I listen to a lot of music, share stories about Asian diaspora around the world, and swim.
