Testing of the MasterCard Clearing Presentment Simulator (MCPS) as well as ATM TestLab and maintaining documentation procedures.

Administration, mentoring and using of testing tools and simulators for payment switches of core banking systems on virtual machines and remote desktops, where all tests have been performed. As a member of SIT and UAT team actively worked with BASE24 classic and BASE24-eps. As a Senior Test Analyst, I was in charge of system integration and user acceptance testing. I was responsible for maintaining our test simulators, developing and executing formal test plans to ensure the delivery of quality software applications, leading and participating in test planning and quality reviewing, overseeing the writing of test scopes/cases/scripts, also analysing, planning, designing, scripting, executing, debugging and reporting defects through the SDLC phases. In the last two years, I focused on complete test automation of virtual ATMs to ensure that upgrading of the base operating system went smoothly.

Testing of the serving GPRS support node (SGSN) and the gateway GPRS support node (GGSN/iGGSN) by simulation of the radio part in the telecommunication network for 2G, 2.5G and 3G. It included preparing test scenarios, testing, detecting & describing errors and reporting. The main focus of my work was the maintenance of Ercom simulators on a daily basis. These simulators were used for the simulation of the radio part of the telecommunication network. Ercom simulators run at separate mainframes as thin clients managed from Solaris server.
