About

I'm Jeff. I run a homelab, write about what breaks and how I fix it, and I'm working through the CompTIA stack. Most of what's here comes out of hardware I own and operate.

What I work with

• Systems: Linux, systemd, journald, and a Proxmox homelab — VMs, a small cluster, backups, monitoring.
• Networking: DNS, subnetting and VLANs, the Cloudflare Tunnel → Caddy → mg-server request path, and CLI diagnostics (dig, ss, curl).
• Automation: Rust and Python for small operations tools, health checks, and reports.
• Security: HTTP headers, SSH and TLS hardening, and auth-log detection, on things I own.

Further out

Past the day-to-day, I’m drawn to AI infrastructure and platform work, open and heterogeneous hardware (FPGA, RISC-V, photonics), resilient off-grid compute and comms, and adaptive, auditable AI systems. Interests, mostly — the kind of thing I’d chase once the foundation is solid.
