Yuni worked on backend systems for game development, focusing on access-control logging improvements in the pheenty/goob-station and ErhardSteinhauer/frontier-station-14 repositories. Using C# and the Entity Component System architecture, Yuni implemented a PreventAccessLogging tag to suppress unnecessary log entries when ghost entities interacted with airlocks. This approach allowed for selective logging, reducing log noise and improving the relevance of security audits. By aligning logging controls across both repositories, Yuni enhanced system maintainability and enabled more efficient incident investigations. The work demonstrated a thoughtful balance between security and performance, addressing both feature development and bug fixes within a short timeframe.
