Summary

With over 20 years as an independent IT consultant, I’ve led large-scale migrations and modernizations for Fortune 500 and global organizations—streamlining operations, tightening security, and cutting costs. I specialize in end-to-end migrations within the Microsoft ecosystem (AD → Entra ID, Office 365, SCCM → Intune, PBX → Teams Voice), delivering scalable, repeatable solutions. My Core Areas of Expertise Include: • Global Tenant Migrations (AD → Entra ID, O365): Led migrations for global enterprises (5K–150K users), Office 365 deployments including Chinese-region (21Vianet). Migrated Active Directory forests and Google Workspace tenants into Entra ID/O365. • Endpoint Management & Deployment: Designed and deployed Intune Autopilot/ADE solutions for Windows and macOS across 12,000+ endpoints in three countries. Completed greenfield builds and migrations from AirWatch/WS1, reducing device provisioning time and licensing overhead. • Automation & Infrastructure as Code (IaC): Built PowerShell/Graph API runbooks and Python scripts to automate Azure workloads, Intune device management, and reporting. Developed Terraform/Bicep code to deploy Azure infrastructure and ensure repeatable consistent results. • Enterprise Voice & Collaboration - Architected Teams Voice migrations for 50+ clients (200–50,000 endpoints), replacing Cisco/Avaya PBXs with Direct Routing (AudioCodes, Ribbon) and Operator Connect. • Azure & Entra ID Security - Hardened multiple hybrid cloud environments (North America, EMEA, APAC) utilizing security baselines, remediating critical vulnerabilities using Microsoft, Semperis, and Quest. Conducted attack path analysis to eliminate privilege escalation paths for Fortune 500 clients.
