Right now I'm a freelance software engineer. I have been working with the Wikimedia Foundation on the future of MediaWiki for over six years, and I consult with other organisations to help them make MediaWiki work for them. I'm a quick learner, and I want to broaden my technical expertise, by working with interesting technology on innovative products that make life easier and more intuitive for people.

When I'm not working, I'm planning my next trip, trying to learn a new language, reading or brewing or drinking beer.

To give you a better idea of the type of work I can do, here are some samples of projects and changes that I'm proud of. I have more samples that previous employers have asked me to share privately only.

  • I implemented a robust import and conversion infrastructure to import data from various legacy systems into MediaWiki's new discussion system.
  • As part of my work on Wikimedia's Living Style Guide I wrote a MediaWiki extension to demonstrate the features of our in-house JavaScript UI framework.
  • In my final year of university, I wrote ROS modules (1, 2) to read from an image topic, detect alphabet blocks on a table, and normalise their position relative to a mechanical arm. Video
