View All ProjectsProfessional Experience
I have spent over a decade building and running infrastructure for enterprise organizations. Here is a bit about my journey and what drives me.
Enterprise Cloud Infrastructure
I have spent over a decade building and running cloud systems for large organizations. My focus has always been on creating infrastructure that stays up when it matters most.
Identity and Access Management
I administer Active Directory, Azure AD, and Entra ID across multiple domains. I manage user identities, roles, service accounts, and access privileges while ensuring seamless integration with on-premises AD.
Security and Compliance
I run Security Attack Surface Analyzer on new implementations, audit AD Security Groups for compliance, and work with security teams on firewall patches and policy enforcement.
Platform Leadership
I lead platform work across both on-premises and cloud environments. I work closely with security, compliance, virtualization, and networking teams.
