System Specifications

  • HYPERVISOR: KVM / Libvirt (RHEL 10)
  • DIRECTORY REALM: FreeIPA (lab.local)
  • AUTOMATION: Ansible Engine
  • CONTAINERS: Podman (Rootless Namespace)
  • ACTIVE VM NODES: 4 Virtual Machines

Engineering Principles

Idempotency First

Ensuring all systems automation scripts and playbooks are repeatable, safe to run repeatedly, and yield consistent states.

Defense in Depth

Isolating services, hardening firewall interfaces, configuring secure DNS parameters, and leveraging rootless namespaces.

Declarative Infrastructure

Maintaining all environment blueprints, services, and configurations under version control as a single source of truth.

Technical Track Record

Homelab Infrastructure & Automation Deployment

ACTIVE LAB PROJECT

Self-Hosted RHEL 9 / 10 Enterprise Cluster

  • Implemented a bare-metal RHEL KVM Hypervisor using Libvirt utilities, provisioning isolated VM nodes with bridged network profiles.
  • Deployed a FreeIPA server (LDAP/Kerberos) to centralize single-sign-on authorizations, host configurations, and BIND DNS zones.
  • Established a private Gitea code registry and Gitea Actions Runner inside rootless Podman namespaces, resolving strict SELinux socket permissions.
  • Built shell automation scripts incorporating the Rclone RC API (`rclone rc vfs/refresh`) to refresh mounted Google Drive directories on a Navidrome container with zero unmount downtime.
  • Routed internal VM nodes through encrypted Cloudflare Zero Trust Tunnels to securely expose endpoints (Gitea, Grafana) without opening inbound ports.
