I'm highly passionate about all things OpenID Connect, OAuth, related technologies, and security in general. I'm involved in the work to create and maintain standards. I'm equally passionate about building and fostering high performance teams to create awesome stuff.
A generalist and quick learner who is deeply fascinated by all kinds of technology. Perhaps surprisingly good soft skills, great with people.
