I'm a Senior Systems Engineer at a fiber ISP and managed services provider in West Virginia. My day-to-day spans ISP core architecture, fiber and VoIP/PBX infrastructure, REST API integrations, and a lot of Python automation that ties it all together.
I build solutions end-to-end and deploy them — real error handling, SSL, monitoring, and production config, not toy snippets. I also handle municipal IT for several West Virginia cities, covering everything from network troubleshooting to Microsoft 365 administration.
Outside of work I run a homelab, self-host most of my own tooling, tinker with Linux (Arch, Gentoo), and build things for fun — from Minecraft servers to personal coding projects!
