A lawyer who becomes mayor is still a lawyer. A doctor who runs a phamacology company is still a doctor. And yes, and engineer who founds a company still retains the core skills and prestige of their hardwon profession.
Or at least, I think they should.
Outside the US, engineering is the same. Within the US, there is no formal board for software engineerig but we can at least informally say one is an engineer if other engineers would recognize them as such. I know people whom graduated bootcamps and could qualify as engineers, albiet inexperienced ones, and those who have finished 4 years of schooling but cannot practice engineering.
The guy in the article was inducted into the Academy of Science and Engineering at 34. Whether that makes him pretigious or not isn't the question, but there is no doubt in my mind that he is an engineer.
A software developer is an engineer the same way a janitor is a sanitation engineer.
