Worked on the aws-samples/generative-ai-use-cases-jp repository, focusing on front end stability and codebase consistency over a two-month period. Addressed two key bugs using React, JavaScript, and TypeScript, first standardizing terminology by correcting a recurring spelling error throughout the codebase to improve maintainability. Subsequently, implemented a fix to ensure the inter-use-case demo popup automatically closes when users navigate away from demo pages, directly enhancing user experience by reducing distractions during demonstrations. No new features were introduced during this time, as efforts centered on bug resolution and laying the groundwork for future enhancements, with all changes tracked and documented.
