Worked on the PaperMC/Paper repository to enhance the reliability of player skin handling by refactoring the logic responsible for applying skin properties to player profiles. Focused on improving the applySkinToPlayerHeadContents method, the work ensured that player skins are rendered correctly by accurately considering the presence of both player ID and name. This targeted update reduced edge-case failures and improved consistency across different game versions. The approach emphasized maintainable, extensible code, lowering the risk for future changes to skin features. Utilized Java for both API and game development, demonstrating attention to cross-version compatibility and robust handling of player profile data.
