  • Firewall and remote-access configuration
  • Hardware procurement and lifecycle management
  • End-user support and training

I have administered more than 50 Linux instances across professional and homelab environments. Most current systems use Ubuntu or Debian, with additional experience using Fedora, Arch Linux, and FreeBSD.

  • SSH access and user management
  • systemd services and scheduled tasks
  • Package, firmware, and security updates
  • Log review and fault isolation
  • Backup and recovery procedures

Identity and access

My work includes user and access management in Windows environments and a self-hosted Authentik deployment that provides SSO, MFA, and application access policies. I am continuing to develop my Active Directory and Group Policy experience.
