I am a website mechanic
I fix broken things. I add on extra features. I make the site do the thing. And I spend a lot less time working on my own site than I ought to.
My usual acronyms include PHP, SQL, JS, CSS. My regular vocabulary is peppered with drush, wp-cli, ifconfig, git, ssh, bash, apache, nginx, composer. Most of my usual contract work is Wordpress, but I also use Backdrop and Drupal, and have dabbled in a variety of others.
