John Calvin
Tyler.
IT and cybersecurity professional specializing in Microsoft Entra ID, identity and access management, and Azure cloud administration.
Combining professional IT support experience with hands-on expertise in Conditional Access, privileged identity management, Azure RBAC, Microsoft Graph PowerShell, and security automation.
ABOUT
Built on IT experience. Focused on cloud security.
I’m an IT and cybersecurity professional with experience in technical support, identity lifecycle administration, access control, and Microsoft 365 environments. My background combines hands-on troubleshooting, identity operations, and a strong foundation in enterprise IT systems.
From 2021 to 2023, I supported physical identity and access management operations at VIP Access Management, including credential administration, access authorization, and audit documentation. At Oatridge Security Group (2023–2026), I supported Windows endpoints, Microsoft 365 users, Active Directory and Entra ID account operations, MFA troubleshooting, and incident resolution using ServiceNow and PowerShell.
My current technical focus is Microsoft Entra ID, Azure administration, identity governance, and security automation. Through independent enterprise-style labs and GitHub projects, I implement and validate Conditional Access policies, phishing-resistant MFA, PIM/JIT access, Azure RBAC, Microsoft Graph integrations, and KQL-based security monitoring. These projects demonstrate practical security administration, troubleshooting, and automation skills.
