PROFESSIONAL SUMMARY

IT executive with 30+ years in infrastructure and cloud — starting as a network engineer in 1995 and evolving through senior engineering and infrastructure architecture roles before moving into the cloud migration and transformation work that defines my career today. Over that arc, I have driven large-scale cloud programs for Fortune 500 companies across pharma, financial services, and analytics. At AWS, led strategic engagements for a $14.7B global healthcare account and shaped $120M in private pricing commitments. At Royalty Pharma and Verisk, personally architected migrations of Active Directory, file services, and .NET workloads to AWS — cutting infrastructure costs, eliminating legacy VPN dependencies, and modernizing identity through Zero Trust. Known for translating complex cloud strategies into business ROI that resonates with C-suite stakeholders, and for shipping results without the fanfare.

VP – IT and Transformation

AWS Cloud & Infrastructure Modernization

•Architected a Microsoft DFS infrastructure spanning multiple AWS regions to fully retire on-premises file servers — eliminating a single point of failure and reducing latency for global users by routing SMB traffic to the nearest AWS node via AD Sites and Services.

•Migrated Active Directory Domain Services to AWS with zero downtime, maintaining uninterrupted authentication for on-premises and remote users throughout the cutover.

•Deployed AWS IAM Identity Center (SSO) federated with Microsoft Entra ID, centralizing access control across the AWS organization and reducing identity sprawl.

Security & Workplace Modernization

•Led a $500K network overhaul replacing end-of-life Fortinet hardware with Cisco Meraki (firewalls, switches, APs), simplifying operations and improving visibility across all offices.

•Eliminated legacy VPN overhead by migrating to a Zero Trust Network Access (ZTNA) model via Zscaler — reducing attack surface and improving secure remote access experience.

•Modernized hybrid collaboration by deploying Microsoft Teams Rooms globally and consolidating VoIP from Nextiva onto Microsoft Teams Calling, reducing telephony costs.

•Implemented Microsoft Intune for MDM and LeapXpert for regulated communication archiving, strengthening governance and audit readiness.

•Deployed FreshService ITSM including the company's first formal asset database and self-service request catalog, reducing ticket resolution time and improving SLA tracking.
