What I'm looking for

I seek a technical role in packet core/4G-5G integration where I can lead outages, drive cross-team solutions, and grow in cloud-native telecom systems.

I am a telecom professional with 10+ years of experience in Packet Core, 4G/5G networks, and international roaming, delivering integration, configuration, and troubleshooting across multi-vendor environments.

At Cisco India I drive PGW, GGSN, SGSN and MME integrations across native and cloud infrastructure, lead outage response and customer escalations, and implemented key enhancements such as N26, MIP6 selection (FQDN), HSS-based P-CSCF restoration, and traffic migrations.

I excel at KPI troubleshooting, cross-team coordination during P1 incidents, and continuous improvement—currently advancing 5G PAY/MAC development using C/C++ and working with the OAI 5G open air interface simulator.
