Kory worked on the SeichiAssist repository, delivering a caching optimization for Player Head URL retrieval. He implemented an unbounded Map-based cache for HeadSkinUrl objects within the PlayerHeadUrlRepository, using Scala and Java to reduce redundant fetches and improve retrieval performance. By refactoring the repository and applying functional programming principles, Kory simplified the codebase and enhanced maintainability. This solution addressed the challenge of scaling user and head data, resulting in faster access and reduced external load. The work demonstrated a thoughtful approach to performance and code clarity, focusing on practical improvements that support both system throughput and user experience.
