Worked on the excalidraw/excalidraw repository with a focus on maintaining stability and correctness in state management. Addressed a critical bug by resolving the app-jotai import path in LocalData.ts, which restored reliable app state persistence and prevented regression in user session handling. Collaborated closely with co-authors to ensure the patch was robust and maintained code correctness. The work was implemented using TypeScript and front end development skills, emphasizing careful attention to state management logic. Although no new features were released during this period, the contributions laid the groundwork for future improvements and refactors in the application’s state management architecture.
