Sort of. I created my own static site generator. It allows me to work faster, fully offline, with version control and on slow hardware (at the time, a 12" Macbook). It made my work much easier than when I did updated content through a CMS. Aside from that, a lot of small optimisations. Sublime Text build systems, shortcuts to switch between projects, SSH aliases, clever dotfile functions, deploy-on-push, and so on.
