I work for IBM as a z/OS System Tester. I was also the SVT System Programmer for about a decade. Since then, I've been testing mostly things at the interface between z/OS software and zSeries software, such as Supervisor, WLM, and so on. I was test lead for HiperDispatch and test architect for SMT-2. I also dabble in python, analytics, and data visualization, and have an interest in system security.
