• Delved into the intricacies of helm upgrade for existing releases using ksctl/ksctl go package.

Performance & Sustainability Focus:

• Gained extensive knowledge on RAPL and non-RAPL estimators for energy consumption, tackling challenges in cloud VM environments.
• Pioneered platform-level addon support, with a successful POC for per-process/container energy consumption metrics.
• Researched best practices for AI Agent tool creation from Anthropic and dived into Nvidia GPU operator blog posts.
• Explored the nuances of grid carbon intensity (average vs. marginal) and the core, uncore, and package zones for RAPL.
• Worked extensively with Kepler, Prometheus, and green metrics, including OCI-based Helm deployments.

System Design & Core Infrastructure:
