James T.
Expert DevOps, VMware Proxmox | Linux/Windows Sysadmin | Cybersecurity
Hey, I’m James. I’ve been a self‑employed business network and server admin for 25+ years, building and supporting critical infrastructure for SMBs and enterprises across the country. I work daily with Linux and Windows environments, VMware and Proxmox clusters, and complex networks that simply cannot go down. Many of my core clients have trusted me with their systems for over 20 years, because I focus on rock‑solid uptime, clear communication, and long‑term relationships—not quick fixes. I specialize in infrastructure that has to “just work”: virtualization, storage, networking, security, and web hosting. Recent work includes fully automated multi‑node VMware + vSAN builds using IPMI, PowerShell, and Python; high‑availability WordPress platforms with 50,000+ active members and 99.999% uptime; and deep network redesigns with Unifi, VLAN cleanup, and clear documentation your internal IT team can actually use. At the enterprise level, I’ve redesigned infrastructure for a 6‑billion‑dollar publicly traded company, implementing redundant firewalls, VMware hosts, dual fiber to AWS with VPN failover, and power redundancy—while reducing monthly management costs by over 25,000 and consolidating 20+ servers to 8. I’ve also delivered CMMC v2 cybersecurity implementations for government contractors, combining policy, technical controls, and staff training into a practical, auditable program. If you’re looking for top‑tier help (not the cheapest bid) with cloud infrastructure, virtualization (VMware/Proxmox), network security, database and web hosting, or compliance‑driven environments, let’s talk. Send a brief overview of your current setup, pain points, and goals, and I’ll come back with a clear, no‑nonsense plan to stabilize, simplify, and scale your infrastructure. When you hire me, here’s what you can expect: 1. Click the “Invite” button to share your job and a brief overview of your environment. 2. Once we’re matched on Upwork, we’ll jump on a call (Zoom or phone) to walk through your current setup and objectives. 3. I’ll ask targeted questions to clarify requirements, risks, and success criteria so we’re aligned on exactly what “done” looks like. 4. I’ll send you a high‑level written plan outlining the approach, milestones, and estimated hours or budget. 5. When we agree on the plan and timeline, I’ll execute, keep you updated as we go, and document everything so your team isn’t left in the dark. If this sounds like the level of help you’re looking for, click “Invite” and let’s get your infrastructure stable, secure, and easy to manage.
