Worked on stability and deployment improvements across google/perfetto and elastic/cloud-on-k8s, focusing on reducing production risk and streamlining operator workflows. In the Perfetto repository, addressed a traced_probes CPU spin issue by implementing robust period validation in C++, introducing a one-hour maximum and expanding unit tests to cover edge cases. For Elastic Cloud on Kubernetes, enhanced Helm charts by adding an extraObjects field, enabling injection of additional Kubernetes resources such as ConfigMaps and Secrets during deployments. All changes maintained backward compatibility, updated documentation, and ensured comprehensive test coverage, demonstrating strong skills in DevOps, Kubernetes, Helm, and system programming.
