Worked on the openedx/frontend-app-authn repository to refactor the registration form user experience, focusing on accessibility and reliability. Leveraged React and JavaScript to introduce ARIA roles, enhancing inclusivity and compliance with accessibility standards. Improved the alignment of username suggestions using SCSS to ensure a consistent interface across devices. Addressed potential race conditions by implementing cancellation of in-flight real-time username validation requests, which increased the robustness of the onboarding process. The work emphasized frontend development best practices and accessibility, resulting in a more reliable and user-friendly registration flow without introducing new bugs during the development period.
