Infrastructure that stays up, and stays quiet.
IT Infrastructure, Network and Security Staff and SAP Basis Staff at PT Traktor Nusantara, based in Jakarta. I work as part of the IT infrastructure team behind 500+ users, 15 branch offices and 60+ virtual machines. My work spans network security, virtualization, Microsoft 365 and identity, and backup and disaster recovery. I've led modernization projects including the move from on-premise Exchange to Microsoft 365, a switch to cloud-based EDR, and a Cisco Meraki rollout across our branch offices.
