Worked on the azerothcore/azerothcore-wotlk repository to enhance the Kurzen Medicine Man NPC by fixing a critical bug and implementing health-aware AI behaviors. Leveraged SQL and database management skills to strengthen DB and SAI integration, enabling scalable tuning of NPC actions. Developed smart scripts that allow the NPC to cast Renew, Heal, and Inner Fire, as well as retreat and call for assistance when health is low, aligning behavior with expected WotLK patterns. This work improved encounter reliability and gameplay balance, demonstrating a solid grasp of game development principles and robust NPC scripting within a data-driven architecture.
