• 1. Managed 5G SA gNB setup and validation in lab environment, including CU-DU split and ORU (n78, 8T8R integration).
• 2. Led end- to-end testing for VoNR/VINR, attach, throughput, and handovers (Xn/NG) across RAC NR builds using UE simulators and real UEs.
• 3. Led end-to-end validation and feature testing for LTE RAN across multiple software releases, ensuring compliance with 3GPP standards and release stability.
• 4. Designed and executed 500+ test cases covering feature validation, performance KPIs and real-world
• scenarios using real UE setups and simulators such as Viavi TM500, Keysight UE Sim, Amantya Real UE automation framework.
• 5. Build and maintained automation test suites using WITA (Robot Framework) for scenarios such as Handovers, RRC Re-establishments, VoLTE, RRC & ERAB Drops, etc, increasing regression coverage by 40%.
• 6. Created keywords in Robot for extensive validation of test scenarios, reducing validation turnaround time.
• 7. Developed XML-to-Excel parser tool using Python with embedded logic to parse PM counters, compute KPIs, and generate visual reports, cutting manual post processing effort by 90%.
• 8. Implemented SNMP-based automation scripts to monitor KPI thresholds and infrastructure health, improving anomaly detection and fault isolation.
• 9. Performed deep protocol and log analysis using Wireshark and XCAL to identify root causes of system-level issues and improving overall product stability.
