I also work for the Wikimedia Foundation, but I use my staff account for edits made in that official capacity. Take a look at that page for more about my work at the Foundation. Before November 2014, I had been using this account to do my official work as staff as well, so many older grant discussions here on Meta will show official edits by me.
I have been a practicing (volunteer) Wikipedian for many years; my home wiki is the Hebrew Wikipedia, but I make occasional contributions on the English Wikipedia as well. I have a strong background in software engineering, and an abiding interest in literature, education, open access, linked data, and library science.
Dhole -- a Ruby gem providing ActiveRecord mapping of main Mediawiki DB entities and relationships
I've contributed some features and patches to Mediawiki-Gateway, the older Ruby Mediawiki API client gem. I still know it well, and am happy to help if you're trying to do something on Mediawiki in Ruby.
