DevOps Engineer and Cloud Architect building scalable, automated infrastructure. I specialize in Kubernetes orchestration, CI/CD pipelines, and cloud-native architectures β and I write about it all on Medium.
- π§ Infrastructure as Code β Terraform multi-environment management
- βΈοΈ Kubernetes β Cluster architecture, service mesh, eBPF networking
- π CI/CD Pipelines β Jenkins shared libraries, GitHub Actions, GitOps
- π Zero-Trust Security β Network policies, L7 filtering, egress control
- π Observability β Prometheus, Grafana, distributed tracing, Hubble
- π± Always shipping β hands-on demos with every article I publish
Multi-cloud architecture, cost optimization, high availability patterns, serverless and container services
EKS/GKE/AKS, service mesh (Istio, Cilium), GitOps (ArgoCD), progressive delivery, eBPF networking
Multi-environment management, modular design, Crossplane CRDs, compliance as code
Pipeline architecture, container registries, canary/blue-green deployments, automated rollbacks
Metrics, alerting, distributed tracing, log aggregation, Hubble flow visualization
- π Zero-trust Kubernetes networking with eBPF β CILIUM-in-action
- π Progressive delivery pipelines with canary analysis β ARGO-ROLLOUTS-in-action
- π Service mesh security with mTLS and traffic splitting β ISTIO-in-action
- βοΈ Kubernetes-native cloud provisioning with Crossplane β CROSSPLANE-in-action
- π Event-driven autoscaling with scale-to-zero β KEDA-in-action
- π€ AI-powered DevOps workflows for debugging and audits β devops-ai-workflows
Each project includes a full Medium article walkthrough, automation scripts, and a working demo you can run locally on Minikube.
