What I'm looking for

I’m looking to own end-to-end systems support—cloud identity, servers, security, and backups—while partnering with stakeholders to deliver reliable, SLA-driven service.

I’m an IT Systems Administrator with 6+ years of experience supporting end users, servers, and infrastructure across multi-site and multi-vendor environments. I focus on Microsoft 365 and identity administration (Microsoft Entra ID / Azure AD, Active Directory), while also managing Windows/Linux servers, DNS, and DHCP to keep services running smoothly.

Across my roles, I’ve owned backups, disaster recovery, firewall administration, and endpoint protection, and I coordinate with vendors to drive issues to resolution. I also support ITSM workflows using Zoho ticketing (incident, problem, and request fulfillment) and oversee consistent delivery by managing IT support engineers across regions—always communicating clearly and troubleshooting calmly under pressure.
