Coraline Ada Ehmke

I am a well-known speaker, writer, open source advocate and technologist with over 20 years of experience in developing apps for the web. I have been focusing on software development with Ruby and Rails since 2008. I work diligently to promote diversity and inclusivity in open source and the tech industry. I was recognized for my work with a Ruby Hero award in 2016. I am best known as the creator of the Contributor Covenant, the most popular open source code of conduct in the world (with over 35,000 adoptions including JRuby, Swift, F#, GitLab, and Rails.)

I am the co-author (with Naomi Freeman) of the upcoming book The Compassionate Coder, a guide to practicing empathy as a software developer. Slated for release in late 2018, you can learn more about the book at compassionatecoder.com.

I serve on the board of directors for Ruby Together, a non-profit that funds development of critical Ruby infrastructure like RubyGems.org and RubyToolbox.com. I was formerly on the board of RailsBridge, an organization that teaches marginalized people web development with Ruby and Rails.

I record music in my home studio and have released three albums, all available widely on iTunes, Amazon, Spotify, and Google Play. You can hear samples and get links to listen or buy at alittlefirescarecrow.com.

I started my gender transition in March of 2014. I am very public about my journey in the hopes that I can make the way easier for those who come after me.
