I'm Joseph Rosenbaum — a Systems Architect and AI Engineer based in Dallas, TX building production AI infrastructure, self-hosted inference, and operator-facing automation for MSP operations.

I built Manifold, a Go LLM gateway routing org-wide AI traffic with priority queues, fallback chains, and full telemetry; RC-AT, a .NET 10 WPF desktop app plus server that automates RingCentral-to-Autotask ticket intake; and 7 MCP servers that expose the MSP stack to AI agents.

I also run a 55+ model local inference stack on AMD Ryzen AI MAX+ 395 hardware with active Unsloth QLoRA fine-tuning, manage 25+ VMs on Proxmox, and ship tools like Conduit, SSHubble, stack-dashboard, and Pulse into real production workflows.

Systems Architect / AI Engineer @ PCT Support

📍12820 Hillcrest · Dallas, TX 📅Oct 2021 → May 2026 ⚙Infrastructure + AI Automation

Designed and deployed Manifold — a production Go LLM gateway serving org-wide AI traffic with OpenAI-compatible APIs, Dex JWT auth, priority routing, fallback chains, SQLite telemetry, and Prometheus metrics.
Built RC-AT — a production .NET 10 WPF desktop app plus Node.js/Express server that captures RingCentral Phone data via Chrome DevTools Protocol, runs a 3-layer semantic embedding pipeline, infers ticket fields via LLM, and submits directly to Autotask.
Engineered a self-hosted inference cluster on AMD Ryzen AI MAX+ 395 with 128 GB unified RAM, a 55+ model catalog, Lemonade inference server, Gemma 4 multimodal stack, benchmark suite, and active Unsloth QLoRA workflows.
Built 7 custom MCP servers (TypeScript/Node.js) integrating Autotask, Datto RMM, IT Glue, SaaS Alerts, Pax8, M365 Graph, and OneDev — exposing the MSP stack as tool-callable endpoints for AI agents.
Built Conduit — a Playwright-based Microsoft 365 automation platform with token broker, GDAP lifecycle management, bulk admin consent, async job queueing, and durable handling of MFA and dynamic SPA flows.
Built SSHubble — an SSH reverse-tunnel relay and MCP server for AI-agent-driven remote support sessions with ephemeral keys, approval gates, NetBird provisioning, and full audit transcripts.
Built stack-dashboard — an operational MSP metrics dashboard with dual-model AI chat, 23 tools, and live data from Datto RMM, Autotask, IT Glue, SaaS Alerts, Microsoft 365, Pax8, and RingCentral.
Design and operate 25+ VMs and LXC containers on Proxmox with Caddy, Cloudflare tunnels, Veeam/PBS backups, and automated git-pull-on-restart deployments.
