Worked on the HeyPuter/puter repository to enhance the reliability of the username change workflow by addressing a critical bug in the rate-limiting service reference. Applied backend development and database management skills to refactor and simplify SQL queries, improving both readability and maintainability of the codebase. Focused on JavaScript for API development, ensuring that user update operations remained stable even under increased load by removing an edge case in the rate-limiting logic. Maintained clear traceability through a well-documented commit, demonstrating a methodical approach to problem-solving and code quality. The work resulted in a more robust and maintainable user update process.
