Many years ago I developed simple webpages with PHP (PHP nuke at the time). Last year I created 2 RoR apps. The first one following Michael Hartl's tutorial and the second one it was a personal project. Now I'm involved in a new business project. It's currently only using wordpress, but we really need to create our own app to automate many of the processes. I'm trying to develop the needed platform by myself. I'm loving it!
