Relocated to Seattle after a decade in San Francisco, and always looking for new projects. I like to learn in the field of information science and to help others learn there too. Sometimes this takes the form of teaching, management, advising, recruiting, or software platform development. My strongest powers are still in engineering management, platform engineering, recruiting, and data.
