What I'm looking for

I seek a hands-on telecom role focused on VoIP/SIP engineering, SBC/OXE troubleshooting, and carrier integrations within a collaborative, growth-oriented team.

I am a Telecom Engineer with extensive hands-on experience in VoIP, SIP call flows, SBCs and Alcatel-Lucent OXE systems, focused on delivering reliable voice services and root cause analysis.

At Movate Technologies I troubleshoot complex OXE software and IP phone issues, recreate customer environments for RCA, manage PBX deployments and integrations with vendors like Cisco and Avaya, and contribute to knowledge bases and team training.

Previously I managed carrier escalations, SIP signalling, SMS platforms, and NOC operations across global voice networks, maintaining SLA compliance and improving troubleshooting efficiency through tooling and documentation.
