Ceara Chewning developed and enhanced AI-driven differentiation features for the code-dot-org/code-dot-org repository, focusing on both backend and frontend systems. Over six months, Ceara delivered robust chat interfaces, session management, and curriculum-aware prompts, integrating React and TypeScript for dynamic UI components and Ruby on Rails for scalable backend APIs. The work included modernizing AWS dependencies, refining database schemas, and implementing automated testing to ensure reliability and maintainability. By addressing user onboarding, policy-driven feature toggling, and opt-out compliance, Ceara’s contributions improved user experience, supported scalable adoption, and reduced release risk, demonstrating depth in full stack development and test automation practices.

September 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.
