Did a lot of work on Wikipedia with media, usability, and internationalization. As with all such things that merely facilitate volunteers, it’s hard to say what’s mine or put dollar values on it. But it’s touched at least a billion lives, and facilitated a large fraction of a media library that will likely outlive me. I’ve worked on minor stuff that was foundational to Google’s commercial offerings, but I think that isn’t as high impact and probably someone else would have done that as well or better. For the Wikipedia stuff, for good or ill, I owned some of those decisions.
