- Validated and optimized RF performance for 5G NR and LTE systems, supporting carrier-grade deployments serving millions of users, ensuring high throughput, low latency, and stable mobility.
- Performed detailed RF and PHY/MAC layer analysis using XCAL, QXDM, and Wireshark, analyzing RSRP, RSRQ, SINR, CQI, modulation schemes, HARQ behavior, and scheduler performance, improving RF stability and reducing call drops.
- Executed end-to-end RF call processing validation for 5G NSA/SA, LTE, VoLTE, and VoNR, identifying RF-related failures and improving session success rates and mobility robustness.
- Conducted handover and mobility optimization (intra/inter-gNB, IRAT, EPS fallback), reducing RF-induced failures and improving edge-cell performance.
- Validated RF performance under load using Spirent Landslide, simulating thousands of subscribers and analyzing RF KPIs to ensure production-grade scalability.
- Supported conducted RF testing and system-level validation, correlating UE-side RF measurements with network-side signaling to identify hardware-software interaction issues.
- Collaborated with hardware, firmware, RF, and systems teams to debug RF impairments, timing issues, and performance bottlenecks, accelerating issue resolution from lab to production.
- Ensured 3GPP compliance across RF, RAN, and Core interfaces, supporting certification-ready deployments.
- Built Python-based automation to extract RF KPIs, analyze logs, and accelerate RF troubleshooting workflows, reducing debug time by 30%+.
- Delivered 99.9%+ service availability through proactive RF monitoring, root-cause analysis, and performance tuning.

04.2019 - 07.2022
- Validated 4G LTE and 5G NR wireless system performance, with a strong focus on RF behavior, signal quality, and call processing stability across NSA and SA deployments.
- Performed RF-aware call flow and signaling analysis across S1, N2, N3, N6, and F1 interfaces, identifying RF-induced failures impacting data throughput, voice quality, and session reliability.
- Conducted conducted RF and system-level measurements, analyzing RSRP, RSRQ, SINR, CQI, BLER, and modulation schemes to diagnose coverage gaps, interference issues, and performance degradation.
- Used spectrum analysis and UE log tools (XCAL, QXDM) to correlate PHY/MAC-layer RF measurements with network signaling, improving root-cause accuracy for RF issues.
- Executed handover, mobility, and carrier aggregation validation, tuning RF and mobility parameters to reduce call drops, handover failures, and edge-cell performance issues.
- Performed packet-level and RF-correlated debugging using Wireshark and tcpdump, tracing SIP, NGAP, GTP, and RTP flows to isolate RF-triggered call setup and data session failures.
- Collaborated closely with hardware, firmware, RF, and QA teams to debug RF-to-system interaction issues, accelerating issue resolution from lab validation to production readiness.
- Automated RF test analysis and KPI extraction using Python and shell scripts, reducing manual log analysis effort and improving debug turnaround time by 30%+.
- Supported pre-certification and compliance testing, ensuring wireless performance met 3GPP requirements and operator acceptance criteria before commercial rollout.
