Reverse Sweep Consulting is the small company I created a few years back so I could perform work for customers in mainframe computing.
I am Lennie Dymoke-Bradshaw, an ex-IBMer but also ex a couple of other companies as well. I have spent most of the last 49 years working with IBM mainframes from a System 370/145 to the IBM z16 processors. I work primarily in the z/OS arena now, and specialise in security and encryption work.
