About

I am an IT professional with hands-on experience as a System Administrator, specializing in user access management, endpoint security, and IT infrastructure support. I work daily with technologies such as Microsoft Intune, Ivanti, Active Directory, and Office 365 to ensure secure, efficient, and reliable system performance for end users across the organization. My role involves supporting and managing desktops, laptops and networks while ensuring compliance with security policies and providing prompt technical support. I have a strong understanding of Group Policy, Azure AD, DNS, DHCP, VPNs, and endpoint protection strategies, and I continuously seek ways to improve IT operations through structured troubleshooting, monitoring, and documentation. I’m passionate about maintaining high system availability, helping users stay productive, and upholding the integrity of the IT environment. With a growing interest in cybersecurity and IT compliance, I aim to evolve into roles that blend infrastructure expertise with security management.
