Ensure all user interfaces and digital components strictly comply with WCAG 2.1 AA guidelines, AODA requirements, and municipal digital standards across web, iOS, and Android platforms.
Partner with cross-functional development teams, solution architects, and project managers to plan, estimate, and deliver work packages.
