I resolve complex MSP infrastructure, identity, Microsoft 365, and endpoint support issues.

I'm currently supporting multiple client environments at Itechra, resolving complex endpoint, application, server, network, and Microsoft 365 issues as a Tier 2 IT Support Engineer.

I administer Microsoft 365, Entra ID, Exchange Online, SharePoint, Active Directory, permissions, licensing, MFA, and access controls. I also troubleshoot DNS, DHCP, VPNs, firewalls, wireless networks, email delivery, and remote access.

Over more than 11 years in the MSP industry, including eight years at Technology Business Solutions, I've handled IAM, PAM, provisioning, onboarding and offboarding, systems administration, monitoring, backup restoration, and Tier 2 support across diverse client environments.

I bring 15 years of IT experience spanning helpdesk, service desk, technical support, data analysis, and team leadership. I document resolutions clearly, manage incidents to SLA requirements, and work with vendors and escalation teams to close complex issues.
