Technical Support / Help Desk Coordinator delivering reliable identity and infrastructure support.
United StatesWhat I'm looking for
I’m a Technical Support / Help Desk Coordinator with 12+ years supporting desktops, servers, and infrastructure. I’m SLA-driven, averaging 35–50 tickets/week with a 95% SLA, and I’m strongest when issues need repeatable fixes—runbooks, imaging, and clear onboarding/offboarding.
In my current role, I’m the escalation point for desktop/server, ACLs, virtualization, and identity issues. I also architected a BizTalk 2020 infrastructure deployment for 200 users and coordinated procurement, deployment, validation, and cross-team documentation—so teams can move quickly without sacrificing reliability.
I’ve led VMware cluster migrations (12 hosts) with zero downtime and authored runbooks that cut post-migration incidents 40%. I’ve also driven network and identity improvements—renumbering IPs for ~450 endpoints to eliminate conflicts, and leading domain migration plus biometric time-clock rollout to remove time-fraud exposure.
