At OpsWerks, I support production Data & ML platform infrastructure across multi-tenant Kubernetes and multi-cloud environments, including distributed compute, ML orchestration, and inference services.

I troubleshoot Kubernetes workloads through resource, scheduling, networking, service, and application issues using logs, metrics, events, and cluster diagnostics. I’ve also improved production workload efficiency through utilization analysis and right-sizing, delivering approximately 20–30% infrastructure cost savings while maintaining reliability.

Previously, I supported data-processing and orchestration platforms for data engineering and ML teams, investigating Spark, Flink, and Airflow failures, performance issues, and service health. I respond to incidents, perform root-cause analysis, and distinguish infrastructure failures from workload-specific issues.

I’m pursuing DevOps and Platform Engineering opportunities focused on cloud infrastructure, automation, Kubernetes, and infrastructure reliability.
