At PT Pertamina Patra Niaga MOR 4, I manage onsite networks, MikroTik, Cisco network development, Zabbix monitoring, routing, switching, and WLC.
Previously, I led IT maintenance at PT Infra Solusi Indonesia, coordinating network monitoring, troubleshooting, endpoint support, Office 365, VPNs, IP cameras, IP phones, and IT asset management.
I've supported infrastructure at JD.ID and RTV, including Active Directory, DNS, email, data center systems, firewalls, Wi-Fi, warehouse devices, and network operations.
