Kiryl Filatau
Worked on the GoogleCloudPlatform/PerfKitBenchmarker repository to deliver scalable AI benchmarking and Kubernetes infrastructure improvements. Over five months, developed features such as GPU-accelerated EKS scaling, Kubernetes node pool management, and cross-cloud metadata support, using Python and YAML for backend development and configuration. Refactored flag handling and test structures to reduce misconfiguration risk and improve maintainability, while introducing logging and code quality enhancements for better observability and developer workflow. Leveraged AWS, Kubernetes, and DevOps practices to optimize cluster scalability and reliability, enabling faster, more cost-effective benchmarking. Addressed bugs related to resource leakage and configuration drift, supporting robust cloud benchmarking.
