Maybe there are just students. My school did not teach us Git, our programs were graded by algorithms and teachers.

I had built simple but not trivial programs like a Raytracing engine in C, a basic shell with AST, globbing etc.

When I started looking for my job, I just took the time to migrate some of these projects to Github. The project was already finished and unversioned, so I just

git init git remote add git add . git commit git push

Not the best, but it was the best I could do at that time.
