  • Fluent with Kubernetes primitives, Helm templating, and advanced networking (CNI, network policies).
  • Strong .NET Core microservices & messaging (Azure Service Bus / Event Hubs).
  • Autoscaling expertise (HPA, KEDA ScaledObjects / ScaledJobs, queue-based throttling).
  • Solid grasp of Envoy / Istio concepts, ingress controllers, DNS, TLS, and L4 / L7 traffic shaping.
  • PowerShell & Bash scripting; container build optimization with Docker BuildKit.
