I lead product and development at Keepsafe for Unlisted, a private phone number app for texting and calling. I previously created and ran Unlisted (then known as LineUp) as an independent developer for five years before it was acquired by Keepsafe in 2017.

In past years, I earned a degree in Physics from UC Berkeley but ultimately enjoyed software development and entrepreneurship more. After teaching myself iOS development, I have worked several years as an iOS developer on some great apps in San Francisco and Berlin. Some of these apps were featured in Apple's WWDC keynote, regularly ranked in the Top 50, or were featured by Apple in the Apps of the Week or Best New Apps categories.

Apps

I have been fortunate to work on some great native (mostly Swift now, but previously lots of Objective-C) iOS apps for myself, clients, and employers. Several of these apps also involved Ruby on Rails backend work. You can find some recommendations given to me for this work on my LinkedIn profile.

Please note: With the exception of Unlisted, which is owned by my employer, I am no longer involved in the active development or maintenance of these apps, since they belong to previous employers or clients. All intellectual property rights remain with the apps' respective owners.
