PROFILE
Viktor Barna
Viktor Barna enhanced accessibility across the instructure/canvas-lms repository by building an Accessibility Issues Dashboard and delivering targeted UI improvements. He developed a new API endpoint using Ruby on Rails and TypeScript to aggregate accessibility issues by course and rule type, enabling streamlined triage and remediation. On the frontend, Viktor implemented React components with robust state management via Zustand, focusing on semantic HTML and ARIA attributes to improve screen reader support. His work included refining table structures, visible labels, and navigation for assistive technologies, resulting in a more inclusive LMS experience and reducing compliance risk through modular, maintainable code changes.

5 Commits • 1 Features
Sep 1, 2025September 2025: Delivered comprehensive LMS accessibility enhancements for the Canvas LMS UI to improve screen reader support and semantic markup. The work focused on visible labels for inputs, screen-reader captions, semantic table structures (th with scope), and aria-describedby associations, with removal of redundant landmarks to streamline navigation for assistive technologies. Targeted improvements were implemented in Course Summary and Syllabus areas, including a table caption, improved syllabus table headers, and ARIA relationships for module links. These changes reduce accessibility risk, elevate user experience for assistive technology users, and support broader WCAG conformance across the product. Business value: enhanced inclusivity, broader user adoption, and lower QA/regression risk for accessibility features. The work is traceable to a defined set of commits across the instructure/canvas-lms repository.

Aug 1, 2025Month: 2025-08 — Canvas LMS (instructure/canvas-lms) monthly summary focusing on business value, key technical feats, and overall impact. Key features delivered: - Accessibility Issues Dashboard: consolidated accessibility improvements into a single dashboard. Preview now displays only the specific element with the accessibility issue; introduced a new API endpoint to summarize accessibility issues by course and rule type; added GroupedIssueSummary UI component to present issues categorized by rule types with loading/error handling and navigation controls. Major bugs fixed & stability improvements: - Resolved fragmentation in accessibility reporting by consolidating issues into one dashboard, enabling consistent triage across courses. - Enhanced previews to highlight the exact problematic element, reducing remediation guesswork. - Implemented reliable endpoint-driven summaries and a resilient UI flow (GroupedIssueSummary) that handles loading states, errors, and navigation for remediation tasks. Overall impact and accomplishments: - Accelerated accessibility remediation across courses by providing end-to-end visibility (dashboard, course-level summaries, and rule-type grouping). - Streamlined triage workflow, enabling faster prioritization and remediation for compliance-related issues. - Improved maintainability through a modular approach (dashboard, API endpoint, and UI component) that scales with course catalog growth. Technologies/skills demonstrated: - Backend API design and integration (new accessibility issue summary endpoint). - Frontend componentization and data-driven UI (GroupedIssueSummary) with robust loading/error handling and navigation. - Data aggregation by course and rule type, enabling actionable insights for remediation teams. - Emphasis on accessibility and inclusive design as a core business value driver.
