Senior RAN Engineer at Amdocs (Client: T-Mobile) (2020-03 – Present)

Support T-Mobile RAN testing, validation, and performance analysis across 8+ nationwide metro markets (Seattle, Chicago, Milwaukee, Detroit, Spokane)-directly impacting KPIs tracked at national and director scorecard level.

• Lead RAN feature validation and acceptance for software upgrades and FOA rollouts-executing pre-production functional testing, stability checks, and regression validation before wide-scale release to millions of subscriber sessions.
• Feature validation: VoLTE/VoNR stack, EN-DC, Massive MIMO beamforming, SON (ANR/MRO/PCI), QCI bearer handling.
• KPI pass/fail gating: used counter thresholds to accept or reject software releases. Post-integration stability monitoring: tracked RRC, E-RAB, HO success rates pre/post changes.
• Execute end-to-end RAN integration and acceptance testing for new macro sites, small cells, carrier additions, and DAS deployments-producing milestone packages, test reports, and post-integration KPI validation documentation.
• Troubleshoot complex L2/L3 RAN issues including mobility failures, bearer-setup problems, VoLTE drops, and connectivity faults through Layer 3 log review, call-flow analysis, counter correlation, and Wireshark/packet trace analysis.
• Conduct performance, capacity, and load analysis across multi-layer LTE/5G NR clusters-resolving throughput bottlenecks, congestion, and load imbalance through parameter optimization and traffic equalization.
• Design, review, and validate RF datasheets (RFDS) and plumbing diagrams for NSBs, LTE overlays, small cells, and DAS sites; select antenna configurations (Hex-port, 8-port, 12-port) aligned to coverage and capacity objectives.
• Built network observability workflows using True Call, ActixOne, IMNOS, and OneData-enabling early degradation detection, KPI trending dashboards, alarm/counter analysis, and proactive network health reporting.
• Developed and maintained Python and SQL-based automation scripts for KPI reporting, counter analysis, and performance tracking-reducing manual effort and enabling faster decision cycles.
• Authored technical test documentation including test plans, validation checklists, and post-integration reports; presented findings to T-Mobile engineering and director-level stakeholders.
• Researched 3GPP RAN standards (Rel. 15/16/17) and cloud-native RAN evolution-providing implementation-focused feedback on AI-native RAN, Open RAN, and 5G SA architecture during strategy reviews.
• Recognized by T-Mobile managers and directors for sustained NSD/Overlay program delivery and for driving cross-functional actions that measurably improved service stability and customer experience.

RF Engineer IV-Nokia RAN Testing & 5G NR Optimization at Sublime Wireless (Client: Sprint) (2018-07 – 2020-03)

• Established Nokia AirScale Massive MIMO and 5G NR readiness validation in the Philadelphia market using 64T64R radio testing throughput, latency, beam performance, MU-MIMO (DL/UL), and EN-DC/NSA deployment readiness; documented findings and communicated results to customer teams.
• Executed Nokia LTE and 5G NR parameter testing and optimization: A3/A5 mobility events, MLB/MRO, EN-DC thresholds, cDRX, TTI Bundling, PUSCH Hopping, Channel Aware Scheduling, and handover parameters across Bands 25, 26, 41, and n77.
• Performed RAN functional and performance testing for VoLTE networks across Philly Metro, South Jersey, and Delaware-independently managing clusters and confirming Accessibility (99.9%) and Sustainability (99.7%) KPI targets.
• Executed KPI analytics and RAN troubleshooting using Nokia ENIQ-S SQL queries, TEMS, XCAL, XCAP, Windcatcher, and GNet-Tracker-analyzing PRB utilization, RTP gaps, SRVCC, BLER, UL interference, and Layer 3 signaling.
• Diagnosed VoLTE SIP access failures and call drops using Wireshark and Windcatcher; fine-tuned A3 offset, PCI, and neighbor parameters to resolve instability-delivering documented root cause and corrective action reports.
• Validated multi-band LTE load balancing across Band 26/800MHz, Band 25/1900MHz, and Band 41/2.5GHz TD-LTE for Nokia, Samsung, and Ericsson RAN-confirming traffic management compliance and spectral efficiency improvements.
• Audited VoLTE parameters for GPL compliance, managed vMME IP configuration changes, and validated QCI 1, 5, and 9 feature activation-coordinating results with customer-facing Nokia and Sprint teams.

RF Optimization Engineer-Nokia BBU Migration Testing at Sublime Wireless (Client: AT&T) (2017-09 – 2018-06)

Performed post-migration RAN testing and KPI validation for 741+ eNodeBs in the Washington market following large-scale BBU migration from ALU BCEM to Nokia AirScale FSM4-confirming stability and performance through structured test procedures.

• Executed KPI test analysis covering RRC Setup Success Rate, E-RAB Drop Rate, S1/X2 HO Failure Rate, intra/inter-frequency mobility, DL/UL throughput, and VoLTE call quality post-FSM4 deployment-escalating anomalies to Nokia field teams.
• Provided structured root cause analysis for VoLTE drops SRVCC failures, RTP gaps, SIP access failures, and poor SINR/MOS-using drive test data, PM KPIs, and Layer 3 log analysis to produce actionable remediation reports.
• Used Nokia NetAct OSS, ALU SAM OSS, BTS Site Manager, Actix Analyzer, Emil, Wireshark, QXDM, BTS Log, and TTI Trace for commissioning, troubleshooting, and post-integration test documentation.

NPO Specialist-Nokia RAN 4G Launch, Testing & Optimization (Client: Vodafone) at Nokia (2016-08 – 2017-09)

Directly employed by Nokia to lead end-to-end 4G launch, RAN testing, and RF optimization for Vodafone UP East-successfully launching and validating 1,600+ 4G sites in one of India's most complex telecom circles.

• Executed structured KPI validation and RAN acceptance testing post-launch-confirming improvements in CSSR, RRC Failure Rate, E-RAB Drop Rate, and HO Failure Rate through counter-based testing and field-validated parameter tuning.
