• Service Delivery & Team Leadership: Lead, mentor, and coordinate the IT service desk and infrastructure support team. Enforce ITIL-aligned incident, problem, change, and request management so SLAs are met and end users get consistent, high-quality support.
  
• System Reliability & Incident Response: Act as the primary escalation point for critical infrastructure incidents across network, firewall, servers, and endpoints. Lead troubleshooting, restoration, and root cause analysis, and make sure preventive actions are implemented and documented.
