I'm a software engineer and architect. I care deeply about using technology to empower individuals and organizations, especially giving people control over their digital lives, using a combination of web technology, open data formats, and cryptography.
I am the Executive Director of VotingWorks. Previously, I led Engineering at Clever, Seller Engineering at Square, the Identity Team and Mozilla Persona project at Mozilla. I used to be an academic and ran a couple of small bootstrapped startups.
I'm on the Board of Creative Commons, a non-profit organization that enables low-friction, legal sharing to expand creativity and knowledge.
I created and maintain the Helios Voting System.
I co-created the RDFa structured data standard.
