Worked on the PathOfBuildingCommunity/PathOfBuilding-PoE2-v2 and PathOfBuildingCommunity/PathOfBuilding repositories, delivering features and fixes that enhanced calculation accuracy and item support for end-users. Developed chill stacking mechanics with updated calculations and configuration options, and expanded item data parsing to support Breach Rings with quality constraints. Addressed core combat mechanics by fixing ailment calculations and resolving Divine Blast scaling inconsistencies, improving reliability for melee-focused builds. Collaborated on documentation to ensure maintainability and traceability of changes. Utilized Lua scripting and performance optimization techniques throughout, focusing on game development challenges related to combat mechanics, data parsing, and the accuracy of in-game calculations.
