Worked on the reearth/reearth-visualizer repository to enhance search reliability by implementing server-side normalization of user input for search queries. Addressed issues where leading or trailing whitespace in name or email searches caused inaccurate or failed results, improving the overall user experience. The solution involved a focused backend change using Go and GraphQL, ensuring that all search inputs are trimmed before processing. This targeted update was delivered as a single, isolated commit, making it straightforward to review and maintain. No bugs were fixed during this period, and the work demonstrated careful attention to code quality and maintainability in backend development.
