At ST (Smart Tech), I lead monitoring and escalation for SMS platforms, analyze SMPP route health, and perform DLR analysis and trace interpretation. I also work with internal teams on issue RCA and support new interconnect provisioning.
At Smart Tech Messaging PTE. LTD., I monitored live SMS and voice traffic, handled SIP/SMPP account setup, and troubleshot delivery failures and VoIP issues. I also managed A2P messaging over SMPP, including routing and rate changes.
At VR Telecom, I performed route testing and VoIP fault diagnostics, investigating SIP response errors, fake IVRs, and FAS. At Excitel Broadband, I monitored and resolved issues across AAA, routers, switches, and OLTs, and contributed to an EPON-GPON migration project.
Earlier at Excitel Broadband, I provided L2 support for service degradation, speed, and browsing issues, and trained L1 agents while tracking SLA and FCR metrics. My telecom operations work includes SIP, SMPP, SS7, MAP, and GTT.
