PROFILE

Derek Yau

Worked on the GoogleCloudPlatform/k8s-config-connector repository to deliver and enhance Bigtable AppProfile management for Kubernetes environments. Focused on building new resource types, implementing a core controller, and refining the resource lifecycle, including CRUD operations and CRD regeneration. Introduced Data Boost Isolation support, expanded test infrastructure, and improved observability through enhanced logging and gRPC client options. Used Go, YAML, and Kubernetes extensively, applying skills in API development, backend engineering, and cloud infrastructure. Addressed API consistency by cleaning up response data and aligning test artifacts, resulting in more reliable deployments and streamlined validation of Bigtable AppProfile features in cloud-native workflows.
