Ah, no, I didn't mean to share my perspective as "this is the correct way, yo shall do as me". It's just my perspective and formed by my own experience and work structure.

As it comes up here from time to time, I work as a sysadmin, and have my side academic gig, which I'm the solo developer on a serious piece of code. I design, code, test and verify the whole thing, which is immensely satisfying.

My daily job is very connected to my academic gig, and they feed each other. As a result, I can apply what I've learnt from one to the other. We're a small team, doing a lot of big things, hence my work environment is drastically different than yours.

The gist of my comment was actually, "As I get more experienced, I design and write less code because it's more correct from get go. Then I document it at the level needed and I have something concrete and which can be passed over to anyone who wants to maintain or fork it, and this is equally, if not more satisfying".
