Bill Tyler

Principal Digital Accessibility Engineer, Optum

My passion for creating innovative and usable solutions started "long ago" when usability/user experience were almost unknown and the specialty was just beginning. I've been through many paradigm shifts: command line to windows, local CPU to client server, PC to web, desktop to mobile. Now that I’m at v10.7 of my career I draw upon my many years of experience to the growing field of digital accessibility.
