Hey Ryan, thanks for the questions.

In the past upgrades to the newest versions of MediaWiki were done by the whole team, together. This required testing all extensions, core and Wikia-built and was quite a hassle. Now we have automated tests doing some of that work, plus we've grown we don't need everybody working on upgrades.

Hardest project, hmm… I think every engineer on the team would answer that one differently. Objectively, though, I'd say the hardest project was the visual editor. That thing is a complex piece of software, even though the basic idea is simple enough.
