Über mich
I am a system administrator with over 12 years of experience in leading IT infrastructure projects, managing network and security systems, and deploying VoIP and collaboration solutions. I have an MBA and hold Cisco CCNP Collaboration and CCNA. In my most recent role as a senior system administrator at Asiatech Co., I led a team of nine IT professionals in developing a carrier-grade service structure, achieving a 200% increase in security, a 400% increase in capacity, and a 30% increase in stability. I also analyzed and monitored the virtualization infrastructure, network structure, service and user usage, and behavior using Zabbix and Grafana. Previously, I successfully designed and executed end-to-end infrastructure projects for TAPSI, a leading ride-hailing company, and Nomatec, a major engineering firm. I am passionate about optimizing system performance, aligning IT strategies with organizational goals, and implementing cutting-edge technologies and best practices.
