Looking for examples of modern distributed web applications.
I am trying to understand some examples of complex modern web applications which are used in companies like Kroger , Office Depot or financial companies like Freddie Mac , Fannie Mae etc.
If someone wants to one day get ready to work in these companies as a junior / senior programming what all things they should know
this is a very broad question but some answers will help me ask some more targetted specific questions
I am very interested in learning about designing and making Enterprise Applications
