I’m a consultant, writer, programmer, open source expert, and amateur photographer.

In 2017, I joined NumFOCUS as Projects Director guiding their Open Source Sustainability Program.

I run Authentic Engine, which helps technology companies and open source projects work through challenges related to sustainability, governance, participation, and leadership.

I also host and produce the Recompiler Podcast, which explores technology from an intersectional feminist point of few in a fun and playful way..

From 2011 to 2015, I worked at Mozilla (makers of Firefox and Firefox OS), on various teams and projects. I also served as MozillaWiki module owner. You can learn more about my career experience at LinkedIn.

My community involvement is significant: I co-chaired the annual Open Source Bridge conference from 2011-2015, am a co-founder of the Stumptown Syndicate, a technology education non-profit, for which I served as board member from 2010-2016.

I am co-author of the Citizen Code of Conduct.

In 2012, I was recognized with an O’Reilly Open Source Award.

I live in Portland, Oregon with my wife as well as some cats and dogs. My non-tech activities include Hatha Yoga, gardening, walking, photography, folding origami, learning guitar, and reading.
