Cathy Zhang developed deployment and benchmarking infrastructure for the opea-project/GenAIExamples and GenAIEval repositories, focusing on scalable AI model rollout and performance evaluation. She introduced Kubernetes-based deployment configurations and automated orchestration scripts using Python and Shell, enabling repeatable, production-like benchmarking on Intel Gaudi instances. Cathy streamlined repository structure by removing deprecated directories, reducing maintenance overhead and risk of misconfiguration. In GenAIEval, she implemented end-to-end latency metrics reporting for vLLM, refactoring metrics logic to improve observability during stress testing. Her work emphasized CI/CD, DevOps, and performance monitoring, delivering maintainable solutions that accelerated onboarding and supported consistent, data-driven optimization.
