My most important job responsibilities include participating in FAT, UAT, IOT processes, installing, maintaining and configuring telecom systems under Unix OS, reporting bugs, creating and maintaining testing related documents, providing support for developers or any other team members, providing project-based training for the customer's team regarding various telecom BSS.

I was part of the testing team for several important and big projects; my role was to test the software in various ways: free testing (creativity plays a big part) or specific individual or team tasks. As I performed the testing, I had to categorize and submit the found issues into a database, providing information as detailed as possible and, often, giving directions to the developers on how to fix the issue. The job requires a high level of patience, attention for detail, creativity… Show more I was part of the testing team for several important and big projects; my role was to test the software in various ways: free testing (creativity plays a big part) or specific individual or team tasks.
