I have created over 31 articles (and edited many many more articles) primarily relating to the computer security topic area. Out of these articles, I'm proud of my contributions to a specific few of them:
On the more technical side of things, I mainly work on maintaining the ProofreadPage and PageTriage extensions (I have +2 on ProofreadPage, the Wikisource extension, the PageTriage extension and VideoCutTool). I also operate SodiumBot, help out smaller Wikisources with technical issues, and help maintain a few Toolforge tools. I also work on other tasks/bugs depending on what scratches my itch :)
If you need to contact me regarding something I did on-wiki, I'm Soda on Phabricator and Sohom Datta on Wikimedia Gerrit.
