Transforming Ideas into Infrastructure

Cloud DevOps Engineer building production-grade infrastructure.

As a Cloud DevOps Engineer, I specialize in creating automated cloud solutions that drive operational efficiency. My expertise spans AWS, Azure, Kubernetes, and GitOps workflows.

I run a production-grade homelab — a 6-node Kubernetes cluster with full GitOps, observability, and security. Every tool I showcase here is something I operate daily.

What I've Built

Homelab applications and technical articles on cloud infrastructure.

Homelab Projects

Internal Developer Platform

Self-service namespace provisioning via GitOps. Developers add a config.yaml, raise a PR, and get a fully configured K8s namespace with ResourceQuotas, CiliumNetworkPolicies, RBAC, ServiceMonitor, and Vault secrets — all via ArgoCD ApplicationSet.
