Worked on the facebookincubator/cinder repository to deliver an accessibility enhancement for the version and language selectors, focusing on improving screen reader compatibility and aligning with WCAG guidelines. The solution involved adding ARIA labels to key UI controls, ensuring that assistive technologies can accurately interpret and announce selector options to users. This JavaScript-based front end development effort expanded accessibility coverage, directly benefiting users who rely on screen readers and supporting a smoother onboarding process for diverse locales. The work demonstrated disciplined change management through clear commit and issue traceability, with a targeted approach that addressed a specific accessibility gap in the interface.
