Worked on the semgrep/semgrep repository to address a performance reporting issue in the CLI tool. Focused on improving the accuracy of the slowest rules report by changing its sorting logic from alphabetical to runtime-based, ensuring that developers and security teams can more reliably identify genuine performance bottlenecks. Utilized Python for CLI development and applied targeted bug fixing techniques, validating the update with existing tests to minimize risk and maintain compatibility with the --time flag. Demonstrated attention to detail in debugging and performance analysis, delivering a precise, low-risk change that enhances the reliability of performance triage for end users.
