People's opinions requested. What is the difference between a 'software engineer' and a 'software developer'?

Software engineer is supposed to be a really experienced developer whose worth is now in his ability to decide on what technologies and patterns are most suitable for the given occasion.

One pins a piece of paper on the wall, the other gets the job done.

Historically, there were minor differences between the terms. Engineer - more scientific & professional. Developer - getting shit done.

But nowadays THERE IS NO DIFFERENCE. These are just role names for a programmer. Pretty standard title inflation.

And then for the Australian immi department my position is "developer programmer", please explain this one because I never understood it
