I’ve been working as a New Product Introduction Engineer for Ericsson in the US performing and validating test cases in order to validate W11B /W12B Ericsson releases for AT&T’s network as well as troubleshooting WRAN issues that arose the network when the testing was been performed. As a Customer Support Engineer I developed hands on experience for troubleshooting WCDMA and GSM issues faced in BSS GSM/UMTS/3G domain in Ericsson AXE 810 and CPP systems.
I have enough background and well understanding about radio access network technologies and I already worked in a global environment where I needed to explain and work in another language different to my mother tongue. I also know how a global enterprise work and I’m able to adapt my experience to any other company.
