Worked on the unslothai/unsloth repository to enhance Linux external drive folder browsing by implementing a security-focused denylist for sensitive directories and including mount root validation. Leveraged Python for backend development, integrating robust logic to prevent access to protected paths across both legacy and Hub browsers. Expanded automated test coverage to validate the new denylist behavior and mount-root handling, ensuring regression safety and secure defaults. Improved code quality through pre-commit fixes and collaborative cleanups, focusing on API development and Linux file management. This work reduced the risk of exposing sensitive directories and strengthened the user experience for Linux file browsing.
