Crag enhanced the wowsims/sod project by implementing a data import system that synchronizes build information from Shiromar, ensuring simulations remain current with minimal disruption. He expanded Shadow Priest Phase 7/8 support by adding new builds, gear sets, and test data, while refactoring configuration defaults to reduce maintenance overhead and align with mage presets. In RedHatInsights/rhc, Crag improved CI reliability by updating test automation scripts in Shell and TypeScript to conditionally skip DNF package installation for bootc/image-mode deployments, preventing false failures. His work demonstrated depth in data engineering, simulation configuration, and CI/CD, resulting in more robust and maintainable systems.
