Summary

With over 8 years of experience as a 5G/LTE Modem and eNB Test Engineer, I possess a good expertise in protocol testing, including modem sanity and functional testing of wireless systems. I have a proven track record in assessing network performance, troubleshooting complex issues, and ensuring the stability of 5G and LTE systems. I am adept at using industry-standard tools such as QXDM, PCAT, and Keysight Test Pro- UXM-5G. I am seeking a challenging opportunity as an LTE/5G Engineer to further enhance my skills and contribute to the success of a leading organization.
