Johnyesit
Worked on the cBioPortal/cbioportal-frontend repository over a two-month period, focusing on accessibility enhancements to improve Section 508 compliance and user experience. Delivered targeted updates to forms, controls, images, buttons, and data visualizations, implementing ARIA labeling, tabIndex, and alt attributes to support screen reader navigation and keyboard accessibility. Applied JavaScript, TypeScript, and React to address accessibility issues in both standard UI elements and SVG-based charts, such as OverlapVenn.tsx and CancerSummaryChart.tsx. Additionally, performed a maintainability refactor in BoxScatterPlot.tsx, emphasizing code readability while preserving functionality. No bugs were fixed, with all work centered on new accessibility features.
