Modem System Engineer
Successfully delivered and managed over 12 Inter-Operability (IOT/IODT) sessions, validating and certifying new features and resource allocation strategies with infra vendors (Samsung, Ericsson) through OTA and Lab Testing for carriers (Verizon, DISH, T-Mobile).Validated the functionality and performance of UL-DL throughput, Carrier Aggregation, Mobility, Radio Link-Failure, Beam Management, Thermal Mitigation, Link Adaptation, CDRX, DL 8CC, ULCA, 4X4 MIMO, and more on NRDC (FR1/Sub6 & FR2/mmW), SA, NSA for UE & Fixed Wireless Access (CPE device) across multiple 5G modem releases (Snapdragon SM8650, SM8550, SM8350, and lower-tier chipsets).Coordinated with cross-functional teams, including RF engineers, software developers, hardware designers, QA teams, and infra vendors (Samsung, Ericsson), to meet project timelines and address issues using JIRA.Regularly updated stakeholders on project progress and detailed reports using TestRail. Identified and mitigated project risks related to technical challenges, resource constraints, and timelines, ensuring project continuity.Improved modem performance by 2% through root cause analysis on the PHY layer, validating functional and performance issues across RRC, PDCP, MAC, RLC, and PHY layers.Led automation testing on Samsung and ZTE drops, reducing regression testing time by 60% and software fix verification by 50%. Eliminated manual processes and leveraged LAF cloud to reduce KPI result time by 35%.Delivered four successful demos to Samsung and Verizon by validating functionality and performance on FR1 & FR2 across different Snapdragon modem releases for phones and Fixed Wireless Access (FWA).
