Ryan Liu developed automated Airflow workflows for the GoogleCloudPlatform/ml-auto-solutions repository, focusing on validating and testing Times To Recover (TTR) metrics for GKE node pools. He designed DAGs in Python that trigger label updates, perform disk resize operations, and verify recovery times in Google Cloud Monitoring, enabling repeatable and scalable metric validation. By provisioning ephemeral node pools and integrating with GKE and Cloud Monitoring, Ryan’s work improved observability, reduced manual testing, and enhanced SLA verification for managed Kubernetes workloads. His contributions demonstrated depth in workflow orchestration, cloud computing, and data engineering, establishing robust patterns for infrastructure reliability and performance monitoring.

January 2026: Implemented automated DAG-based testing for GKE node pool TTR via disk resize. The workflow provisions a temporary node pool, triggers a disk resize, and validates TTR metrics in Cloud Monitoring, enabling repeatable performance verification after infrastructure changes. Also improved tagging accuracy to ensure reliable metric labeling and reporting.

Delivered a new Airflow DAG to validate Times To Recover (TTR) metrics for GKE node pools. The DAG triggers label updates and verifies that recovery time is recorded in Google Cloud Monitoring, enhancing observability and SLA verification for managed Kubernetes workloads. This work strengthens reliability, reduces MTTR risk, and establishes a scalable pattern for validating platform metrics.
