What I'm looking for

I’m looking for a high-tier support role where I can own Linux operations end to end—doing deep troubleshooting, RCA, and automation to keep platforms resilient, SLA-driven, and continuously improving operational excellence.

I’m a performance-driven Technical Support Engineer and Systems Administrator with 5+ years optimizing infrastructure resilience in SLA-driven environments. I focus on advanced troubleshooting, root-cause analysis, and systematic log investigation across Linux platforms (Ubuntu/Alpine).

In my current role, I build n8n-based automation workflows and custom chatbots to deflect manual L1 ticket volume by 40%. I also maintain 99.9% uptime by delivering advanced L2/L3 support, stabilizing server performance during peak load events, and standardizing syslog/journald-driven RCA to speed up complex access incident resolution.

Previously, I led an enterprise migration to Google Workspace and implemented SSO across internal services, reducing SaaS subscription costs by 21% and cutting access-related support tickets by 34%. I’ve authored SLA-driven escalation workflows and technical runbooks, automated IAM lifecycle management, and maintained strict security compliance through deep IAM audits in Azure AD—always aiming for operational excellence through ownership and practical automation.
