Here are some websites I've set up at various points as part of different projects I've worked on...
I have three WordPress plugins. Each plugin is completely different. One is mainly an admin area plugin that also has a widget, the other modifies content in all posts and pages, and the last is an easy way to add accordion functionality to a blog with shortcodes.
While I have used WordPress for many years I started to become irked with it as a framework. I still have WordPress websites, and I'm sure I will do more WordPress work in future, but there are other frameworks and ways of coding I'm leaning towards at the moment.
