I love writing small, elegant programs--under 500 lines, say--that do one thing well. Scrape a website and dump the data to a CSV; take a directory full of video files and rename them based on the metadata; poll a JSON API for a retail site to check the price of an item and email someone if it decreases.
I like coding, but it isn't my passion, so it's hard to get my teeth into developing a big web app, or making small enhancements and bugfixes on someone else's. But I always love those little projects when I get the chance to do one. There are lots of non-programming fields that involve this kind of thing (data science, devops, IT, etc.). But are there fields or sub-industries of the software world wherein it's possible to do this kind of old-school scripting for a living?
