Drupal was the only accessible door to me to this entire industry in 2010, with no CS knowledge or available mentors. I was one of those people and I barely fed my family, and I eventually learned PHP, JS, the hosting stack, automating the hosting stack, Varnish and HAProxy, Linux sysadmin, how the internet works, and a decade of topics since.
We all need a door into this stuff, a place to be dropped in to start putting it together. Maybe the OP’s sister in law is totally out of luck, or maybe she’s now got a few of the hundreds of tools she’s going to need to build out a career. Luckily she has a brother in law in the industry, hopefully he’s the helpful type.
