Infrastructure Engineer

A passionate infrastructure engineer with 4+ years of hands-on experience architecting and managing enterprise-grade self-hosted environments. My homelab isn't just a sandbox — it's a production-grade infrastructure running real workloads.

Specializing in Proxmox VE virtualization, VMware ESXi, Linux administration, zero-trust networking via Pangolin ZTNA, and full-stack observability with Prometheus and Grafana. I design systems that are resilient, secure, and operationally efficient.
