Linux systems engineer. Proxmox VE clusters, containers, ZFS/Ceph,
zero trust overlays, and self-hosted AI on hardware you own.

15+ years in production · 5 PVE clusters under management
primary desktop OS: Linux, since 1999

open to fully remote roles · mission-driven and research orgs preferred
I take over infrastructure that arrives with no documentation and no
institutional knowledge, map what is actually running, standardize it
without breaking production, and write the documentation that should
have existed. I would rather do that for an organization trying to move
the world forward than for one that only moves money.

## core focus
- proxmox ecosystem
- PVE cluster design, deployment, and maintenance · HA and quorum ·
ZFS-backed and Ceph storage · iSCSI and NFS shared storage · PVE SDN ·
KVM and LXC guests · GPU passthrough, SR-IOV, and vGPU · Proxmox Backup
Server with verified, tested restores · Proxmox Datacenter Manager for
multi-site control · rolling upgrades and patch cycles
- containerization
- Docker, Podman, Compose, Quadlets, LXC · rootless containers ·
systemd integration · reverse proxy publishing with automated ACME
- migration & modernization
- P2V/V2V of legacy physical and VMware/Hyper-V/Xen workloads into
PVE · end-of-life OS preservation · extracting configuration from aging
network appliances and rebuilding on current hardware · cutovers with
minimal production downtime
- zero trust networking
- Netbird and WireGuard (hub-and-spoke, mesh) · identity-scoped
application access via Microsoft Entra ID and other IdPs · site-to-site
routing and multi-site interconnect
## ai infra
Self-hosted language models and agent tooling, architected so inference
and data stay on organization-owned hardware. No third-party model
provider in the data path, no egress of client records, full control
over retention and access.
- Local inference stacks with Ollama and Open WebUI: model selection, quantization tradeoffs, sizing against available GPU, CPU, and memory on Proxmox hosts.
- Hermes Agent (Nous Research, MIT-licensed) as the agent platform, with a multi-model backend across local models, Nous Portal, and Claude. Local by default; hosted models only where the work requires them.
- GPU-accelerated inference on Proxmox: PCIe passthrough to VMs, device mapping into LXCs, Intel SR-IOV, and NVIDIA vGPU sharing one card across concurrent inference VMs.
- Legacy systems wired into modern agents through custom and community MCP connectors, so clients can ask conversational questions of data that used to require manual export-and-parse.

## experience
Systems Engineer · Twin Pines Technology
2024 to present · MSP serving small and medium businesses across Northeast Ohio
- Operate five production Proxmox VE clusters across three clients, including a three-site, nine-node deployment (~30 guests) and a four-node cluster running close to 50 guests.
- Lead legacy virtualization migrations: aging physical servers and legacy hypervisor workloads into PVE, including end-of-life operating systems preserved intact rather than rebuilt.
- Design cluster storage on ZFS, with Ceph, iSCSI, and NFS by workload; run Proxmox Backup Server with retention policy, verification jobs, offsite sync, and documented restore testing.
- Stood up Proxmox Datacenter Manager across multiple physical sites over a Netbird/WireGuard overlay instead of exposed management interfaces.
- Built zero trust network and application access with Netbird against Microsoft Entra ID and other IdPs, replacing flat site-to-site trust with identity-scoped access.
- Migrate configuration off legacy network appliances and recreate it on UniFi, OPNsense, and pfSense, standardizing on hardware without recurring relicensing cycles.
- Built self-hosted AI agent integrations bridging legacy client systems to conversational access via MCP connectors, keeping inference and data on client-owned hardware.
- Inherit undocumented infrastructure, audit what is genuinely running, surface hidden dependencies before they become outages, and leave durable documentation behind.
Design & Deployment Engineer · Park 'N Fly
2023 to 2024 · kiosk technology on embedded Linux and Android SBCs
- Built and maintained Debian images for embedded SBCs in production kiosk hardware.
- Traveled CONUS upgrading lot entrance/exit kiosks and POS devices, including loop detection relay wiring and digital I/O interfacing.
- Wrote the installation and configuration documentation field teams used on later deployments.
Freelance IT Consultant · Self Employed
2008 to 2023
- Administered virtual environments across Linux KVM/Proxmox, VMware, Hyper-V, and Xen for individuals and small businesses.
- Deployed and supported Windows and Linux servers, workstations, and networks end to end.
- Built virtual network overlays with WireGuard and OpenVPN, including site-to-site routing and firewall migrations.
## homelab
A self-hosted lab run as a continuous testbed for the same stack I deploy professionally.
- compute
- six-node Proxmox VE cluster on AMD EPYC 3000 and Ryzen embedded platforms
- storage
- PVE storage node with 8 × 14 TB RAIDZ2 (~112 TB raw); HP EC200a + drive shelf on TrueNAS as dedicated backup target
- services
- Docker/Podman stack behind a reverse proxy with automated TLS, DNS, monitoring, WireGuard/Netbird mesh
- inference
- Ollama + Open WebUI + Hermes Agent; MCP connectors and GPU passthrough configs are proven here before they touch a client environment
- edge
- 5G/LTE, LoRa, and reflashing e-waste routers and APs with OpenWRT to put them back into service
## how i work
Most of my work starts the same way: an environment nobody fully
understands anymore, a client who needs it to keep running, and a pile
of questions with no owner. The people who built it are gone, the
credentials live in someone's head, and the documentation is a sticky
note from 2016.
So I hold several of these projects at once, because none of them can
move in a straight line. Discovery on one client fills the gaps while
another waits on access or answers. I sequence the work so a blocker in
one engagement never stalls the rest, and everything I learn goes into
documentation durable enough that the next person, or the next me,
never has to excavate it again.
The result: legacy systems land in modern, backed-up, monitored
infrastructure, and "how does this work?" has a written answer.
