About Tommie Shea

Over nearly 30 years in IT, I’ve supported environments ranging from global enterprises to government agencies, working across Active Directory, Office 365, virtualization, storage, networking, and hybrid cloud. In recent years, my focus has shifted toward Azure—designing secure architectures that integrate identity, networking, hybrid connectivity, and disaster recovery in a way that strengthens long‑term stability.My background spans engineering, implementation, transition planning, and risk management. I’m comfortable modernizing legacy systems, integrating them with cloud platforms, and ensuring the end result is reliable, secure, and maintainable. I take a calm, methodical approach to complex environments, focusing on clarity, stability, and doing the work right the first time.I’m at my best when improving systems, solving difficult problems, and helping organizations move forward without unnecessary noise or disruption.Core strengths include: • Azure networking & security (VNets, NSGs, Azure Firewall, ExpressRoute/VPN)• Hybrid identity (Active Directory, Azure AD/Entra, SSO, Conditional Access)• Disaster recovery & high availability (Azure Site Recovery, clustering)• Enterprise infrastructure (Windows Server, VMware, SAN/NAS)• PowerShell & Azure CLI automation• Long‑term architecture, modernization, and system stability
