Professional Summary

Platform engineer with deep expertise in AWS container services — EKS, ECS, Lambda — across 100+ production clusters. I ship automated, secure, cost-efficient platforms using Golang, GitOps, Karpenter, and GitHub Actions. Workloads I've supported: banking, AI, e-commerce, streaming media. Previously at AWS and Kong, now at CBA.

Some Recent Experiences

Senior Systems Engineer – Kubernetes | Commonwealth Bank of Australia

Mar 2024 – Present

  • Led Karpenter migration across 108+ EKS clusters (20+ prod), achieving 30%+ cost reduction; wrote a Golang tool to auto-convert MNG → Karpenter specs.
  • Built automated cluster lifecycle pipelines with GitHub Actions, ArgoCD, Helm, Lambda, EventBridge, and CloudFormation.
  • Delivered zero-downtime EKS upgrades via PDBs, blue/green deployments, apiVersion conversions, and GitOps rollouts.
  • Shifted security left with GHA checks, Calico network policies, and Kyverno enforcement; introduced AWS FIS for automated production resilience testing.
  • Improved observability (Prometheus, Grafana, Fluent Bit) and scaled workloads with VPA, KEDA, and event-driven autoscaling.

Senior Site Reliability Engineer – Kubernetes | Kong

Oct 2023 – Mar 2024

  • Ran multi-cloud Kong Gateway/Konnect on large EKS fleets; drove zero-downtime Kubernetes upgrades and GitOps delivery pipelines.

Cloud Engineer II (Containers) — Containers Specialist | Amazon Web Services

Sep 2022 – Sep 2023

  • Accredited EKS SME: led Docker Swarm → EKS migration in hybrid-secure environments and accelerated Kubernetes greenfield adoption to production in under a third of the planned timeline.
  • Executed mission-critical K8s upgrades (1.17 → 1.27) using blue/green strategies; redesigned failover patterns and consulted on EKS + DB security breach response.
  • Built observability with OpenTelemetry, Prometheus, Grafana, X-Ray, and OpenSearch/Kibana; contributed to EKS tooling, mentoring, and interview loops.

Cloud Engineer (Containers) | Amazon Web Services

May 2020 – Sep 2022

  • Resolved production-critical ECS/EKS issues for enterprise customers; designed container CI/CD pipelines with AWS Code services, ArgoCD, and service meshes (Istio/App Mesh).
