Areas of Expertise

Where three decades of hands-on work has concentrated — enterprise environments at every scale, from small business to state government, and the multi-vendor complexity that comes with them.

01
Microsoft Infrastructure & Systems
The full Microsoft stack — Windows Server, multi-forest Active Directory, Exchange, Microsoft 365, Entra ID, and Intune. Decades of planning, deployment, migration, and the ongoing operational work that keeps it all running.
Microsoft
02
VMware Virtualization
Design, deployment, and administration of vSphere, ESXi, vCenter, and VCF environments. Consolidation, performance tuning, patching programs, and physical-to-virtual migration at production scale.
VMware
03
Hybrid Cloud & Data Migration
Azure hybrid environments alongside on-premises infrastructure, and the migrations between them — server-to-server, physical-to-virtual, on-premises to cloud. The unglamorous discipline of moving data without losing any of it.
Migration
04
Network & Multi-Vendor Infrastructure
Enterprise networking — routing, switching, VPN, SD-WAN — and vendor-neutral work across storage, backup, and monitoring platforms. Most real environments are multi-vendor with complex dependencies; that's the environment I know.
Infrastructure
05
Disaster Recovery & Business Continuity
DR strategy, backup architecture, and continuity plans that have actually been tested rather than merely written. Recovery from outages, cyber incidents, and the failures nobody planned for.
Critical Systems
06
Technical Documentation & Enablement
Runbooks, architecture diagrams, standard operating procedures, and training that teams actually use. Helping organizations not just implement technology but understand and sustain it after the project ends.
Documentation

30 Years of Enterprise IT Leadership

With more than 30 years of experience in enterprise infrastructure support services, I help organizations across Sacramento and Northern California — and globally — build reliable, high-performance IT environments.

My core strengths are in Microsoft technologies, VMware virtualization, and third-party infrastructure products — areas where I bring deep hands-on expertise built over decades of real-world engagements. I also specialize in data migration, technical documentation, and IT training, helping organizations not just implement technology but understand and sustain it.

I've worked on-site and remote, across locations and time zones, for organizations that needed experienced and practical infrastructure expertise. The through-line has been clear guidance, dependable execution, and building technology foundations that outlast the engagement that created them.

I currently place my consulting engagements through Zeektek — a Sacramento-based IT staffing firm I've been proud to partner with since September 2024. In my experience they stand apart from other staffing firms in how genuinely they support their consultants. If you're an IT professional exploring contract opportunities, or an organization looking for top-tier technical talent, I'd encourage you to check them out. View open positions →

Get in Touch

I'm always glad to hear from people working in this space. I'm in a long-term contract at the moment, so I'm not taking on new client projects — but I'm open to conversations about future engagements, recruiters planning ahead, speaking and writing, and anything connected to the work on this site.
