Worked on the DayuanJiang/next-ai-draw-io repository to streamline the user experience by removing the Close Protection feature, focusing on simplifying both the interface and underlying codebase. This involved decommissioning related state management logic, UI components, and associated entries in the language dictionaries, resulting in reduced UI clutter and more intuitive user flows. The cleanup also included targeted localization and asset updates to eliminate dead code, supporting maintainability and easier onboarding. All changes were implemented using React, JavaScript, and TypeScript, with careful attention to documentation and commit quality, reflecting a methodical approach to front end development and internationalization.
