working my way out of the Dunning-Kruger valley
i'm an iOS & fullstack engineer shipping product to billions of users. right now i'm working on TikTok Subscriptions: the features people pay for, and the payment and entitlement systems on the client. i've also led performance and architecture initiatives that make the business more money. sometimes i build side projects.
when i'm away from the computer, you can find me skiing, adding to my slowly outgrowing record shelf, watching & playing sports, or doing the New York Times crossword.
