Ziao Ye enhanced accessibility in the cBioPortal/cbioportal-frontend repository by delivering two features focused on Section 508 compliance over a two-month period. Using React, TypeScript, and SVG, Ziao improved forms, controls, images, and data visualizations to support keyboard navigation and screen readers. The work included adding ARIA labels, tabIndex, and alt attributes to various UI elements, as well as descriptive headers for better screen reader navigation. Ziao also refactored chart components for maintainability without altering functionality. These targeted updates broadened accessibility coverage, reduced compliance risk, and maintained code quality, demonstrating a thoughtful and methodical engineering approach.
