Generally I'm working with Drupal version 7 and usually I use pantheon service for development. I have a few my own modules, but due very weird Drupal's contributing mechanism they are not at Drupal.org, but you can find them at my bitbucket account https://bitbucket.org/inri13666
for example
https://bitbucket.org/inri13666/akuma_core
https://bitbucket.org/inri13666/akuma_metadata
https://bitbucket.org/inri13666/akuma_tokenfield
In my work I prefer to use Drupal's hooks standards to extend or override default functionality (:
Here the samples of my work:

Much of my works is private, and unfortunately I'm unable to share them
