During August 2025, Kaixuan Lee developed real-time collaborative editing features for the source-academy/frontend repository, focusing on enabling seamless team coding within the Playground. Lee integrated the Ace editor with session management, role-based access control, and presence tracking, allowing multiple users to edit code concurrently as owners, editors, or viewers. The implementation leveraged JavaScript, TypeScript, and WebSockets to support live updates and robust collaboration workflows. UI and UX enhancements were introduced to improve the collaborative experience, accelerating development cycles and onboarding. This work addressed the need for efficient, shared editing environments, laying a foundation for higher code quality and faster iteration.
