Worked on the GT-New-Horizons-Modpack repository to enhance coolant behavior by tuning configuration parameters for a specific coolant type. Focused on data-driven improvements, the developer updated the relevant JSON configuration file to improve accuracy and enable future balance adjustments. Leveraging configuration management skills, they ensured all changes were version-controlled and traceable, with clear documentation supporting ongoing maintenance and audits. The technical approach centered on JSON-based configuration updates, allowing for precise, modular tuning without code changes. No bug fixes were addressed during this period, but the work laid a foundation for reliable, maintainable gameplay balance through structured configuration management practices.
