I have developed a strong expertise in test case development, integration, debugging, and lab setup. My experience working with various chipsets (MTK, Qualcomm, Google, Samsung) has given me a unique understanding of the complexities involved in testing. My expertise in developing test cases for signaling verification, reselection, handover, roaming, data throughput, VoNR, and MO, MT, and Conference calls has enabled me to validate network performance and functionality. I am well-versed in Jira issue tracking and have excellent communication skills, which enable me to effectively coordinate with customers and internal teams. My previous experience at Anritsu has provided me with a solid foundation in this field, and my current role at Keysight has further honed my skills. Key Responsibilities:
1. Test Case Development and Integration:
Developed test cases for various chipsets, including MTK, Qualcomm, Google, and Samsung, to ensure compatibility and functionality. Created test cases for signaling verification, reselection, handover, roaming, data throughput, VoNR, and MO, MT, and Conference calls to validate network performance and functionality. Integrated test cases with different chipsets, ensuring seamless testing and validation.
2. Debugging and Issue Resolution:
Identified and debugged issues raised in Jira for existing test cases, resolving defects and improving test case quality. Worked closely with internal teams to resolve issues and ensure timely resolution.
3. Lab Setup and Simulation
Set up lab environments for testing, including configuring simulation tools and equipment. Ensured lab setups were ready for testing, enabling efficient testing and validation.
4. Customer Coordination and Bug Reporting

Coordinated with customers to identify and resolve issues, ensuring prompt communication and resolution. Raised bugs and tracked issues internally, ensuring timely resolution and closure.

Tools: PCAT, PRT, Wireshark, QXDM, CATCS, ELT.
