During December 2025, Booky contributed to the PaperMC/Paper repository by addressing a critical startup reliability issue in Java-based game server environments. Booky implemented a startup guard that prevents the scoreboard from saving when no world is loaded, directly reducing early startup errors and unnecessary log noise. This backend development work focused on optimizing server initialization by ensuring scoreboard save logic only executes under valid conditions, aligning with PaperMC’s stability goals. The solution, traceable to issue #13471, demonstrates Booky’s attention to robust error handling and server optimization, leveraging Java and backend engineering skills to improve the reliability of game server operations.
