Developed and delivered the QR Code Sharing for Live Sessions feature in the excalidraw/excalidraw repository, enabling users to share collaboration links via QR codes directly from the live session dialog. This work involved integrating a new QR code component using React and TypeScript, along with targeted UI/UX design enhancements in SCSS to improve discoverability and ease of use. The implementation leveraged the uQR library to ensure reliable QR code rendering across devices. By reducing onboarding friction and accelerating the invitation process, this feature strengthened live collaboration workflows and improved the overall user experience for collaborative sessions within Excalidraw.
