I'm the Level III IT consultant who works for other MSPs and IT consultancies — the senior hand you bring in for the hard problems junior techs escalate: network redesigns, cybersecurity hardening, server migrations, and emergency triage. 30+ years in the trenches, U.S. Navy trained, Top Rated with a 100% Job Success score. Based in the Chicago area / Northwest Indiana, with remote and on-site coverage nationwide. Where I go deep: - Networking & Security: Design, configure, and secure networks with SonicWall, Fortinet, Cisco/Meraki, UniFi/Ubiquiti, TP-Link Omada, and Netgear — firewalls, VLANs, VPNs, 2FA/MFA, site-to-site bridges. - Servers & Hosting: Nearly 30 years of cPanel/WHM, DNS, POP3/IMAP, Microsoft 365, and Google Workspace; Apache/PHP/MySQL on RHEL/CentOS/AlmaLinux for reliable hosting and maximum uptime. - Systems & Cloud: Windows Server 2025, Windows 11, Linux, and macOS; Azure/Hyper-V virtualization and AWS/GCP deployments — from design through deployment and ongoing operations. - Microsoft Stack: Microsoft 365 administration and migration, Entra, Intune, and Active Directory Group Policy. Industry experience: HIPAA-compliant IT for medical/dental, Dealer Management Systems for automotive groups, secure corporate networks, and structured wiring and access control for warehouses. How I work: Precise and methodical. Project-based engagements first, hourly for smaller targeted work. I bring clear status updates and a bias toward documenting what I change, so the next person — internal or external — can pick up where I left off. I coordinate across internal IT teams, third-party vendors, and contract boards when an engagement requires it. Background: Self-taught IT professional since 1997; U.S. Navy Aircrewman, Patrol Squadron 26 (VP-26), 1990–1995, earning a Navy Achievement Medal for technical expertise on a classified surveillance system.

I help teams turn AI ideas into working, evaluated, product-ready workflows. If you need an LLM app, RAG workflow, agentic prototype, AI product strategy, or a practical build/no-build recommendation, I can help you move from "we should use AI" to a working plan, prototype, and next decision. I bring an uncommon mix of product leadership, UX judgment, and hands-on build fluency: - VP Product Manager, AI in MLIO at JPMorgan Chase - Former VP User Experience, AI across regulated banking workflows - Former Microsoft AI product designer during the Microsoft/OpenAI partnership era - Microsoft Global Hackathon winner - 60 Upwork projects, $200K+ earned, Expert-Vetted - Portfolio across enterprise AI, healthcare AI, financial services, marketplaces, SaaS, and product systems What I can help with: - LLM product strategy and opportunity assessment - RAG workflow design and prototype planning - Agentic workflow design with human-in-control guardrails - AI evaluation plans, success criteria, and readiness checklists - OpenAI / Anthropic / LangChain-style prototype direction - Product UX for AI assistants, copilots, dashboards, and internal tools - Executive-ready AI roadmap, risk, and implementation recommendations Typical deliverables: - AI workflow audit - Use-case prioritization matrix - LLM/RAG architecture sketch - Prototype scope and build plan - Prompt/system design recommendations - Evaluation and quality checklist - Product requirements and implementation roadmap - Working MVP or prototype when the scope is clear I am especially useful when a team has a real business workflow, messy requirements, security or governance concerns, and needs someone who can bridge product, design, engineering, AI capability, and executive decision-making. Best fit projects: - AI prototype or MVP for a defined workflow - RAG or LLM feature inside an existing product - Agentic workflow planning before build - AI readiness review for a product, team, or operation - Product strategy for AI-enabled SaaS, CRM, internal tools, or service operations If you want a flashy demo with no operational thinking, I am probably not the right fit. If you want practical AI work that can survive real users, real constraints, and real decision-makers, I can help.
