Worked on the PaperMC/Paper repository to address a memory management issue in the Combat Tracking System, focusing on backend development using Java. Delivered a fix that capped the number of stored combat entries, introducing a configurable max_entries option and implementing automatic eviction of older entries when the limit is reached. This approach reduced memory usage and garbage collection pressure during sustained combat scenarios, improving server stability and scalability for large deployments. The solution allowed server operators to tune memory consumption through configuration without altering gameplay behavior, demonstrating a practical application of Java and backend engineering principles to enhance system reliability.
