Professional Experience

EPC IT Solutions

  • Chief Technology Officer Jan 2020 - Present
  • Systems & Network Engineer 2019 - 2020
  • Support Specialist I-III 2017 - 2019

Promoted three times in three years on the strength of demonstrated ownership - from entry-level support to final escalation authority for all technical and executive decisions across a 15-person MSP supporting 100+ business clients and up to 10,000 endpoints. Led the company through SOC 2 Type I compliance (2022).

  • Diagnosed and resolved a full production data center outage during a live colocation relocation - rebuilt two failed systems and restored all services within a single 8-hour overnight window with zero client impact or SLA breach; instituted the company's first formal change-management process as a result.
  • Architected and deployed an MCP (Model Context Protocol) appliance giving technicians' AI agents secure access to core infrastructure and business systems - directed a fleet-wide cutover from static tokens to Entra ID SSO with per-employee revocation and audit logging, and SOC 2/HIPAA/CMMC-aware data boundaries.
  • Built a multi-agent AI engineering practice (one AI agent builds, another reviews, human signs off), directing six toolkits turning plain-English requests into guarded API actions across core virtualization, cloud, network, PSA, identity, and documentation platforms - first used to grow disks on 22 production VMs, finished in-guest via PowerShell remoting.
  • Directed AI agents to build a self-hosted document Q&A pilot for a prospective client - an open-weight 120B LLM on vLLM (single 96GB GPU) calling MCP search tools over an OCR'd index of 5,000+ technical documents; an evaluation harness raised top-5 retrieval recall from 41% to 71% and showed the limit was answer construction, not retrieval.
  • Led a four-vendor evaluation and migration of the company's RMM platform across 100+ clients, personally engineering automation scripts, patch policy, and security boundaries; zero service disruption in the pilot, phased rollout underway.
  • Directed a standalone, billed Microsoft Copilot deployment for a client, implementing semantic/vector-based search across Teams and SharePoint with permission-aware data access; achieving full company-wide adoption.
  • Own end-to-end design, security, and tooling strategy for the company's self-hosted colocation data center; lead a 4-person technical team and partner with the CEO on hiring and technical interviewing.
