I have been working in telecommunications as a software tester for over 16 years. I performed functional testing for several years and then I switched to lead whole process of performance testing, where I gained a lot of experience: - testing environment preparation - configuration and installation of software versions - functional verification, logs analysis and bug reporting - performance testing such as load testing, stress testing, crash testing - creation of user documentation - creation of reports for customers - using variety of monitoring applications on Linux and MS Windows to see behavior of the whole system or single module
