Hi,
It's quite interesting to see that after BE in mechanical engineering, you would like to embrace either networking and software as a career.
If I get you correctly then your question is more of development and programming.
Python
Angular JS
Jason
Java
IOS, Mobile Development
IOT technology
These are in demand and have a good future scope.
Under networking, you may pursue CCNA and then move forward with professional or security domains. In parallel, you should think of Cloud Computing as well.
