Marcy Sutton is a US senior software engineer (formerly at Deque Systems and Gatsby) and one of the most cited independent voices on web accessibility — particularly the testing-and-engineering side of building accessible web applications.
Her CourseFlix listing carries Build & Test Accessible Web Apps | Testing Accessibility — a structured treatment of the accessibility-engineering discipline: the WCAG conformance criteria, the assistive-technology testing workflow, the automated testing tools (axe, Lighthouse), and the engineering patterns for making accessibility a real first-class concern rather than a checklist at the end of a project.
Material is paid and aimed at front-end developers ready to take accessibility as a serious engineering discipline. For broader content, see CourseFlix's Web Accessibility category page.
