Services & engagement scope ↗Selected work · 2026
A few examples
of my work.
These projects cover work with Qualys, my rack-mounted server, and coding-agent automation. Each write-up explains what I did and what I learned.
01 · Professional / Vulnerability remediation
Qualys Vulnerability Remediation & Patch Management
I use Qualys to identify systems that need patches, configure deployments, and investigate failed or unclear results. I check installed updates and follow-up scans before considering a finding resolved.

Personal infrastructure
Building my Proxmox rack server ↗
Designed and assembled a rack-mounted Proxmox server with 80 GB DDR4.
The build, VM templates, and how I corrected a link running at 1 Gbps instead of 10 Gbps.
Link speed is not throughput; multiple VMs do not provide host-level HA.
Engineering project · Development & validation
Developing Herdr’s coding-agent workflows ↗
Developed coding-agent routing, worktree isolation, and review workflows.
Tested local-only tasks, hosted-model escalation, and separate review steps.
These tests cover specific workflows. Broader reliability and cost comparisons are still open.
Independent technical services

Career trajectory
My experience
At Biltmore Computers I diagnose and repair computers. At SDNetworks I work on systems administration, patching, monitoring, and technical documentation.
The work below is part of my employment. My independent services are separate and are not endorsed by either employer.
- Jun 2026–present
Systems Engineer · SDNetworks
Qualys patch remediation, PRTG monitoring review, Windows endpoints and servers, domain environments, VMware, remote access, and repeatable deployment procedures.

IT Solutions Specialist · Biltmore Computers
Windows and macOS troubleshooting, storage diagnostics, disk cloning, data migration, BitLocker recovery scenarios, boot repair, malware cleanup, component validation, and clear customer communication. I investigate storage, drivers, encryption, and application requirements before recommending recovery or redeployment.
- 2026 graduate
Cybersecurity + Information Systems
B.S. Cybersecurity and B.S.B.A. Computer Information Systems, with a minor in Accounting, from Appalachian State University.

Client relationships · Biltmore Computers
People come back.
I take that trust seriously.
At Biltmore Computers, I work with returning clients and am trusted to handle relationships that are important to the business. My part is to understand what they need, explain their options, and follow through on the technical work.
Client satisfaction matters to me because people need someone they can come back to. Whether I’m explaining a repair or working through a more involved problem, I want them to understand what is happening and what comes next.
More about my client-facing work ↗This work is part of my role at Biltmore Computers. The reviews belong to the business and its team, not my independent services.
Beyond professional operations
Software & earlier investigations.
Other projects include macOS apps, local AI tools, and troubleshooting investigations.

1099 Tax Planner
I built this app to track contractor income, expenses, estimated taxes, and payments together. It runs on my own infrastructure and helps me plan without treating estimates as final tax results.

Native macOS · Multi-agent AI
Orchestra
A native macOS orchestration platform for autonomous coding and research workflows. Orchestra routes work across multiple local LLMs and persistent specialized agents, pairing local tool use, computer-use automation, OpenCode integration, and resource-aware parallel inference with durable missions and reviewable handoffs.

Software engineering · Native macOS
MemoryPilot
A native macOS app that monitors memory use, local AI workloads, and Parallels virtual machines. It shows why a VM may need to be suspended or resumed before taking action.
Read the full case study
The systems problem
Local models and virtual machines share the Mac’s memory. I built MemoryPilot to help manage that competition without leaving me to guess which workload is causing the pressure.
The safety boundary
Automation starts paused and observe-only. Every action is bounded, identity-checked against fresh discovery, and blocked when state is ambiguous. The app never exposes a generic power-command interface.
The operating view
The dashboard shows memory pressure over time, system responsiveness, detected local-model memory use, and the next likely action. I can see what the app is responding to before changing its settings.

Infrastructure platform
What I’m running at home
My homelab gives me somewhere to host services, practice recovery, test security tools, and work across operating systems without experimenting on client systems.
Personal build · Rack-mounted virtualization
Building the rack server
I designed and built a custom 3U server, configured Proxmox VE, and created a repeatable guest foundation. The engineering work spans physical fit, deliberate management and guest networking, and correcting a 1-to-10 Gbps link-negotiation issue.
This is a single-host learning environment, separate from client work. The case study also covers its limits and what I plan to add.
