At Vodafone, I provide 24/7 first-line support for IoT enterprise customers, troubleshooting mobile network and connectivity incidents across services and network components.

I investigate issues involving IoT SIMs, roaming, data sessions, APN configuration, and service availability through ticket diagnosis, log analysis, and service checks. I document findings and resolutions to strengthen knowledge sharing and operational efficiency.

Previously, I monitored cloud-based IoV projects at Huawei Enterprise GSC Romania, analyzed network performance, supported upgrades and migrations, and coordinated with clients and L2/L3 engineers to reduce service disruption.
