I fix things that are broken. I add on extra features. I make the site do the thing.
My usual acronyms include PHP, SQL, JS, CSS. My regular vocabulary is peppered with drush, wp-cli, ifconfig, git, ssh, bash, apache, nginx, composer, apt-get update.
I work regularly with Sol Design Company. (I'm the one at the bottom, in the hat and black leather jacket.) Also Dogghouse Interactive.
