What I'm looking for

I’m looking to grow with an organization that has a global vision, encourages creativity, and offers opportunities to learn and develop professionally and personally. I’d like to contribute and progress toward decision-making and strategy-formulating roles.

At Infinite Computer Solution, I worked as a Senior System Engineer on the Airtel project, deploying, configuring, and integrating IMS Core nodes. I also tested VoLTE and VoWiFi services and validated call flows.

At ERICSSON, I worked as a Network Engineer supporting RJIO in Jharkhand. I analyzed 4G and 5G KPIs and drive-test reports, then made corrective parameter changes when I found network degradation.

As an RF Engineer at Uniinfo Telecom Services Limited, I tested LTE parameters and throughput for Airtel devices. I also executed mobility tests and wrote SIP functionality test cases.

At Meghnath Telesolutions Pvt Ltd, I worked as an RF/DT Engineer on Airtel’s VoLTE project. I tested VoLTE call logs and KPIs, including CSSR, DCR, and SRVCC.
