About Me:
I am the original creator of the Mainframe courses on Udemy. I have been creating content since January 2017. After seeing my success many other instructors and Training institutes have started their own courses. Most of these are training institutes that just launch courses to earn more and more money.
I am NOT a Training institute. I am an instructor on Udemy. Training institutes just launch many courses under many different topics to earn more and more money. They also have physical training institutes where they teach. They then create content and launch on Udemy to earn extra income.
I do not do this. I only create content related to Mainframes and Electronics. I create content exclusively for my website and Udemy.
You can go to my YouTube channel and you will find free content and courses worth many hours related to Mainframes.

I had 3 courses in 2017

2. JCL

I had announced that I will release 3 more courses soon

2. DB2 SQL

Other instructors started releasing courses under the same title as mine. They added some extra information to make their courses look better.

I have 8 years of experience in Mainframes. I was also the community partner for IBM Z day which was organized by IBM on Nov 21. More than 300 students from this course joined that event. You can search for IBM Z day and on the landing page of the event you will find “Mainframe Nation”, that is me.

So be rest assured that you are learning from an authentic Udemy Instructor and not from a Training institute.

Mainframe Developer | Electronics & Communications Engineer
I am a Mainframe Developer and an Electronics & Communications Engineer.
I have more than 7 years of experience in Mainframes.
I published my first 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 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. I provide the best quality content with professional video editing. You can compare my courses with others and see for yourself.
