PROFILE
Ceara Chewning
Over six months, contributed to code-dot-org/code-dot-org by building and enhancing AI-powered differentiation chat features, focusing on both backend and frontend systems. Leveraged technologies such as React, TypeScript, and Ruby on Rails to deliver context-aware chat interfaces, robust session management, and curriculum-integrated prompts. Improved user experience through UI/UX refinements, local and session storage strategies, and policy-driven feature rendering. Addressed stability by expanding automated test coverage and maintaining test reliability, including unit and UI tests. Managed database schema changes and dependency updates to support scalable AI features, while resolving bugs related to content display and user opt-out preferences for differentiated learning workflows.

Sep 1, 2025September 2025: Key AI differentiation enhancements and opt-out fixes in code-dot-org/code-dot-org. Delivered a new AI Differentiation Chat Floating Action Button (FAB) on the Section Creation Page, conditionally rendered based on AI differentiation policies, and wired into the page initialization to assist users during section creation. Fixed a bug where AI differentiation chat did not respect user opt-out; ensured the diff chat is disabled when aiDifferentiationEnabled is false across the teacher homepage and navigation bar, with corresponding tests updated. This work improves user experience, policy compliance, and testing coverage.

Jun 1, 2025June 2025 — Code-dot-org/code-dot-org: Restored course content UI integrity and stabilized release testing for CSF. Key fixes included reverting text truncation to display full course content and temporarily skipping a flaky CSF initial page-views test to prevent release failures. These changes reduced risk to learners and CI reliability, enabling a smoother release cycle.
