At PT Indosat Tbk, I work in Wholesale Interconnect Billing, handling interconnection for IDD, fixed network and cellular services.
Previously, I worked as a Procurement Assistant at PT Indosat Tbk. I performed procurement from Purchase Request/Shopping Cart through Purchase Order issuance, including negotiation, proposal drafting and contract support.
My procurement work focused on IP/MPLS equipment such as Metro Ethernet, switches and routers. I also reviewed SAP and SRM implementation, business processes and LOA.
Earlier, as a Cellular Technician at PT Indosat Tbk, I performed operation and maintenance duties for GSM/CDMA/3G networks and core equipment, monitored network performance, and handled customer complaints.
