I am the developer of WPCleaner, a tool designed to help with various maintenance tasks, especially repairing links to disambiguation pages, checking Wikipedia, fixing spelling and typography, and helping with translation of articles coming from other wikis. I'm using it to automatically fix some issues on meta with my bot account WikiCleanerBot.
Some time ago, I was working on the Jmol project. Jmol is a Java molecular viewer for three-dimensional chemical structures. Features include reading a variety of file types and output from quantum chemistry programs, and animation of multi-frame files and computed normal modes from quantum programs. I have written a MediaWiki extension to display chemical structures using the Jmol applet, the Jmol Extension, which is probably outdated now.
