Infrastructure Live · 30+ Sites Running Now

I don't just
advise on AI.
I run it.

One and Done. Rapid prototyping. Your eureka moment — then we build it. We brainstorm one on one until you see what's possible. Then I build it fast, hand you the keys, and you own it completely. No retainer, no lock-in, no dependency.

Not consulting theory.
Delivered infrastructure.

Every capability listed here is running in production. Right now. I know it works because I depend on it daily.

AI Integration — Real, Not Demo

25 live production websites integrated with Claude AI. Rate-limited, themed, cost-tracked, and centrally managed via a single backend I built and operate. Not a widget I installed — a system I architect.

🔒

Zero-Trust Network Security

10-node Tailscale mesh across Mac, Windows, Linux, Azure, and mobile. Every device on the tailnet. SSH, RDP, and application access — encrypted end-to-end, no open ports, no VPN appliance to manage.

Redundant Remote Desktop

Self-hosted RustDesk relay on DigitalOcean provides full GUI desktop access to any machine — as a backup when Tailscale is unavailable, or for clients who need screen-share access. Two paths in. Zero lockouts.

What this means for your business:
Your team accesses every resource — servers, desktops, shared drives, internal apps — from any device, any location, with zero exposed attack surface. No VPN client to configure, no IT ticket to get access.

Finally. Actually anywhere.

Not a marketing line. The infrastructure to back it up.

01
Every device is on the same secure network
Tailscale assigns every node a stable private IP. Mac at home, Windows at the office, Linux server in Amsterdam — they all see each other as if they're on the same LAN. No configuration changes when you move.
02
SSH and RDP require no open ports
The server has no port 22 or 3389 exposed to the internet. Connect via Tailscale IP and the WireGuard tunnel handles the rest. Attackers scanning the internet find nothing. You connect instantly.
03
RustDesk as the backup path
Self-hosted RustDesk relay on DigitalOcean provides full desktop GUI access — for moments when Tailscale isn't available, or for clients who need screen-share access without joining the tailnet.
04
AI and data follow you automatically
Shared memory and state sync via GitHub keeps every node updated. The same AI context, project state, and working environment — on every machine — without manual sync.
Real Scenarios — This Works Now
Client Site → HQ
Emergency remote fix
Critical system down at a client location. SSH from iPhone via Tailscale — diagnose, patch, restore — no open firewall ports, no VPN appliance. Resolved before the client escalates.
Remote Consulting
Full office access from anywhere
Working a client deliverable from a hotel in Chicago. Laptop tunneled into HQ servers, databases, and internal apps. Commits pushed, deliverable sent — indistinguishable from being on-site.
Home → Office Machine
Full desktop. Any screen.
RustDesk into the office Windows machine from home. Full desktop, all files, SQL Server, every app running. IT opens zero firewall rules. Access granted in under 60 seconds.

25 sites. One AI backend.

John Elia

Twenty-plus years building and operating enterprise infrastructure — most recently at one of the nation's largest hospital systems, where I've been recognized with Exceeds Expectations two years running, the highest rating available. The work spans Azure, DevOps, CI/CD, .NET, Red Hat Linux, IIS, enterprise AI governance, and production platform operations in a regulated environment where reliability is non-negotiable. Before that, eleven years running all of IT for a regional clinical laboratory later acquired by Northwell Health — VMware, SAN, disaster recovery, HL7 integrations, 85,000 outbound faxes a month, 20,000 calls across three locations, and every network circuit from T1 to SIP.

What you're looking at right now is the proof. This site, the 10-node Tailscale mesh, 25 live AI-powered chatbots across production websites, a self-hosted Claude API backend, multi-agent infrastructure running across five machines — all of it built by hand and operating in production today. LIBCSYSTEMS LLC brings the same discipline to client work: not a proposal, not a slide deck — implementation, ownership, and results. If that's what your business needs, the conversation starts at ai@liai.us.
