Dan Bjorge

I'm VP of Product Architecture at Deque Systems, where we build tools to help make software more accessible to folks with disabilities. I lead engineering efforts and standards across the company's product division, and I co-maintain axe-core, an open source accessibility testing engine with billions of downloads. I also represent Deque in the W3C WCAG 2 task force.

Before Deque, I spent over a decade at Microsoft. I most recently worked on Accessibility Insights, an open-source toolkit that's helped ~100,000 developers find and fix accessibility issues, where I represented Microsoft in the W3C Accessibility Guidelines working group. I've also worked on the Windows Engineering System and on the Windows networking stack, including as the owner of BITS, the data transfer engine underlying Windows Update and serving over a billion devices.

Outside of work, projects I'm proudest of include a community Slay the Spire mod I led with nearly 100 contributors, a volunteer recordkeeping system I built for Seattle Humane that replaced paper records and integrated with the shelter's animal tracking software, and an Android app for detecting push notification ad abuse that reached 6 million users before Android built the feature into the OS.
