I'm David Holder, a technology executive with 16 years of experience building and scaling IT infrastructure for a mid-sized SaaS company. I've spent my career at the intersection of practical engineering and organizational strategy, growing from a one-person helpdesk into leading a team responsible for the infrastructure, identity, networking, and business systems that keep a thousand-person remote company running.
I think carefully about systems. Whether that's an enterprise AI governance architecture, a Proxmox homelab running on a mini-PC in my basement, or a workbench I built from scratch in my garage, the underlying impulse is the same: understand how things work, build them well, and document what you learn.
This blog is where I think out loud. You'll find deep dives on self-hosted AI infrastructure, homelab projects, enterprise architecture, open source software, and occasionally woodworking and whatever else has captured my attention. I don't stay in one lane and I'm not going to pretend to.
I live in the Chicago suburbs with my spouse and kid. When I'm not in front of a terminal I'm probably in the shop.
