Worked on the pheenty/goob-station repository, delivering both a gameplay feature and a backend security fix within a month. Addressed a critical authorization issue in the mail system by correcting argument order in the access check, ensuring validation against the intended entity and preventing potential bypasses. Added new reptilian vocal emotes, integrating sound assets, localization strings, and entity tags, and updated configuration and prototypes to support seamless gameplay inclusion. Utilized C#, YAML, and asset integration skills to implement these changes. The work demonstrated a focus on both backend reliability and user experience, with careful attention to localization and gameplay integration.
