I am an Electronics & Communications Engineer and a Mainframe Developer.
I published my first course on Udemy course in Jan 2017. There were no courses about Mainframes on Udemy at that time.
I have since released 5 courses on Mainframes. Over the time the content of all these 5 courses has been consolidated into 2 courses.
The first course titled TSO/ISPF is an introductory course about Mainframe Technologies. It is meant for those who have no knowledge about Mainframes and want to have a head start in this field. It covers TSO/ISPF in detail and other Mainframe Technologies like JCL, VSAM, CICS, COBOL. The second course covers JCL in detail.
All my courses are hands on practical training.
