Worked on enhancing the Nautilus extension within the ublue-os/bazzite repository to streamline the process of adding files to Steam. Focused on improving reliability and security by replacing os.system with os.popen for more robust command execution and implementing MIME type validation to ensure only appropriate files are added. Quoted file paths in callbacks to prevent shell-related issues, further strengthening input handling. Leveraged skills in Python, extension development, and Gnome development to address common failure modes, reducing user friction and support overhead. The work contributed to more dependable file integration workflows and supported smoother release cycles for end users.
