Responsible for ensuring stable end-to-end service delivery across IMS and EPC network elements and contributing to overall IMS network stability through proactive issue resolution and collaboration with cross-functional teams.

• Conducted end-to-end SIP/IMS call flow analysis for AT&T VoLTE/VoWiFi networks, encompassing UE registration, call setup, call release, and supplementary services.
• Analyzed SIP, SDP, RTP/RTCP, and Diameter signaling using Wireshark, NetScout, and IRIS to identify and resolve network issues.
• Executed functional, system integration (SIT), sub-system integration (SSIT), and regression testing across IMS and EPC network elements including P-CSCF, I-CSCF, S-CSCF, SBC, TAS, HSS, MRF, MME, SGW, and PGW.
• Validated over 50 VoLTE scenarios including 2-way and 3-way calls, conference calls, SRVCC/CSFB, video calls, MSRP chat, and file transfer, ensuring compliance with 3GPP and AT&T network standards.
• Developed and implemented automation scripts for Android real devices and simulators to streamline VoLTE testing processes.
• Collaborated with AT&T network engineers, OEM vendors, and internal development teams to perform root cause analysis (RCA) and accelerate defect resolution.
• Reduced defect triage time by 30% through analysis of SIP, SDP, RTP/RTCP, and Diameter signaling using Wireshark, NetScout, and IRIS.
• Improved call success rates to over 99% in pre-production environments through debugging and resolution of protocol-level issues.
• Decreased manual test execution cycles by 40-50% by designing and executing automation scripts for VoLTE testing.
