About Me

Software Development Engineer II at Workday, based in Vancouver, BC, Canada.

I build the automation that keeps enterprise-scale Big Data infrastructure running reliably and at fleet-wide scope. My work spans distributed storage and compute systems that production workloads across the organization depend on.

What I focus on:

  • Fleet lifecycle engineering: OS/kernel rollouts, controlled maintenance windows, and end-to-end upgrade workflows across thousands of nodes.
  • Resilient automation pipelines: Config-driven, GitOps-style systems that make infrastructure changes auditable, repeatable, and safe to roll back.
  • Observability and reliability: SLA/SLO-oriented metrics and infrastructure-as-code backed alerting that gives teams confidence in what they ship.

North Star: "Infrastructure that scales without friction, fails without surprise, and recovers without intervention."
