Worked on the harvard-edge/cs249r_book repository, delivering features that enhanced interactive content, PDF generation, and in-browser database capabilities. Over four months, implemented advanced syntax highlighting, improved UI/UX for blog and quiz modules, and enabled robust PDF creation with jsPDF, focusing on appearance streams and error handling. Refactored diagram rendering and flashcard systems for reliability, and laid groundwork for WebAssembly-based SQLite integration, optimizing memory management and worker thread support. Used JavaScript, Python, and WebAssembly to address cross-platform deployment, content indexing, and visualization challenges, resulting in a more maintainable codebase and improved user experience across web and offline environments.
