DevOps Engineer and Cloud Architect building scalable, automated infrastructure. I specialize in Kubernetes orchestration, CI/CD pipelines, and cloud-native architectures — and I write about it all on Medium.
- 🔧 Infrastructure as Code — Terraform multi-environment management
- ☸️ Kubernetes — Cluster architecture, service mesh, eBPF networking
- 🚀 CI/CD Pipelines — Jenkins shared libraries, GitHub Actions, GitOps
- 🔒 Zero-Trust Security — Network policies, L7 filtering, egress control
- 📊 Observability — Prometheus, Grafana, distributed tracing, Hubble
- 🌱 Always shipping — 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
- 🐝 Zero-trust Kubernetes networking with eBPF — CILIUM-in-action
- 🚀 Progressive delivery pipelines with canary analysis — ARGO-ROLLOUTS-in-action
- 🌐 Service mesh security with mTLS and traffic splitting — ISTIO-in-action
- ☁️ Kubernetes-native cloud provisioning with Crossplane — CROSSPLANE-in-action
- 📈 Event-driven autoscaling with scale-to-zero — KEDA-in-action
- 🤖 AI-powered DevOps workflows for debugging and audits — devops-ai-workflows
Each project includes a full Medium article walkthrough, automation scripts, and a working demo you can run locally on Minikube.
