Professional

Systems, not slides.

I design and run infrastructure — Windows Server, Active Directory, Linux, Azure, and VMware. The kind of work that's invisible when it's done right, which is exactly the point.

01

Windows Server

Designing and running Windows Server environments — from single-box deployments to multi-site infrastructure.

  • Server 2016–2022
  • Group Policy
  • DNS/DHCP
  • Patch management
  • High availability
02

Active Directory

Identity is the foundation everything else sits on. Domain design, trust relationships, and getting the boring stuff airtight.

  • Multi-domain forests
  • GPO design
  • AD security hardening
  • Migrations
  • Hybrid identity
03

Linux

Comfortable across distributions, from a single hardened box to fleets managed at scale.

  • RHEL / Ubuntu / Debian
  • Shell scripting
  • systemd
  • Networking
  • Automation
04

Azure Cloud

Moving workloads to the cloud without moving the problems with them — architecture that's actually maintainable.

  • Azure AD / Entra ID
  • VMs & networking
  • Cost optimization
  • Hybrid cloud
  • IaC
05

VMware

Virtualization infrastructure that stays boring in the best way — predictable, resilient, easy to hand off.

  • vSphere / ESXi
  • Cluster design
  • Storage & networking
  • DR planning
  • Capacity management
