👋 I’m a product designer, podcaster, and writer, currently living in San Francisco.

Right now I’m designing native mobile apps at GitHub. Before GitHub, I co-founded Spectrum, a platform for large-scale communities to have better public conversations. Spectrum was acquired by GitHub in November, 2018.

Before Spectrum I designed payments experiences at Facebook, working across Facebook, Messenger, WhatsApp, and Instagram. I originally cut my teeth as the first product designer at Buffer.

I also co-host the Design Details Podcast, a weekly conversation about design process and culture. Design Details is part of Spec.fm, a podcast network for designers and developers, which I co-founded in 2015.

You can find me on Twitter where I talk about design and development, or on GitHub where I’m building in the open, or on Figma where I’m exploring how plugins can automate the tedious parts of interface design.
