At Ericsson Global India Pvt. Ltd, I work on Vodafone UK 4G/5G RAN, using counter-based root cause analysis to improve 5G incident resolution by 30%. I also use KPI degradation analysis and parameter tuning to maintain LTE E-RAB establishment success at 95%.

I build daily and weekly KPI trend reports and dashboards in Power BI, ELRI and UNISON, improving stakeholder visibility of network trends by 40%. I monitor live networks on ENM and MYCOM and coordinate with the operator, OEM and engineering teams to close trouble tickets within SLA.

Earlier, at Kolkata Telecom Support & Service Pvt. Ltd, I reduced call drop rates by 20% through coverage, interference and signal-quality analysis. At Steelman Telecom Pvt. Ltd, I supported radio planning, site integration and LTE, VoLTE, VoWiFi and IMS performance testing.
