They developed and tested changes to ensure UX components met Mastercard accessibility standards, engaged in technical discussions to refine visual UI designs and code implementation, and provided crucial support to consumers by debugging issues and guiding frontend implementation. Additionally, they planned infrastructure to enable applications to determine the source of a user's culture for optimal user experience and contributed to the architecture proposal for a new application, covering both frontend and backend aspects.
