During August 2025, Kaixuan Lee developed real-time collaborative editing for the source-academy/frontend Playground, enabling multiple users to code together with session management and role-based access controls. The solution integrated the Ace editor with React and Redux, leveraging WebSockets for presence updates and seamless concurrent editing. Lee enhanced the user interface to support clear collaboration cues and streamlined onboarding for team workflows. This work, delivered as the Sessions Overhaul, addressed the need for efficient cross-team development and improved code quality through shared editing. The implementation demonstrated depth in frontend architecture, collaborative editing patterns, and robust session management using TypeScript and SCSS.
