What I'm looking for

I seek a technical support or systems engineering role where I can own escalations, improve processes, mentor peers, and work in an SLA-driven, collaborative environment.

I am a self-motivated technical consultant with over 9.5 years delivering onsite and remote L1/L2 support, incident management, and system administration across enterprise environments.

I have hands-on experience administering Windows Server (2012–2022), Active Directory, DNS, DHCP, Group Policy, Microsoft 365, Citrix environments, MDM solutions (Workspace ONE, Intune, AirWatch), and endpoint management tools like Ivanti.

I specialize in owning escalations, developing knowledge-base content, coordinating with vendors and cross-functional teams, and ensuring SLA compliance while improving service desk processes and documentation.
