Over a two-month period, contributed to both the cncf/toc and NVIDIA/KAI-Scheduler repositories by delivering targeted features focused on security, compliance, and resource management. Developed comprehensive HAMi CNCF Incubation Self-Assessment Documentation for cncf/toc, detailing security practices and compliance controls to streamline audit readiness. In NVIDIA/KAI-Scheduler, implemented per-container GPU memory isolation using HAMi-core, enhancing multi-tenant reliability and predictability for GPU workloads. The work emphasized robust documentation, governance artifacts, and strict resource enforcement, leveraging Go, Kubernetes, and containerization technologies. Collaboration and code quality were prioritized through multi-signer approvals and thorough design reviews, ensuring alignment across project stakeholders.
