I can relate because of 2 things; 1. I also played a lot of legos during my childhood & loved it. 2. I have a similar "preference" on configurations & shell-profile. (ie. overall setup)
At work, I am the only person who has a personal configuration & automation package (ie. dotfiles) at my director's level organization. (Maybe there is another one or two at most)
Not only that, I also have a nearly complete automation to provision a new machine, virtual or otherwise using the same code. (usually maintained by make && make install)
I update things regularly. It has bunch of "utility" scripts. As it being a $FAANG company, once in a while, here and there, people stumble on scripts/solutions/docs (also markdown). There were even occasional CRs (code-reviews / pull-requests) I received.
