The Open Speakers Database is a crowdsourced database for connecting people with regional experts on Open Access, Open Education, and Open Data. This is also intended to be a resource to encourage event organizers to invite geographically diverse speakers to their meetings and conferences. The database is powered by Sheetsu and you can find the code on Github.
OpenCon 2017's do-a-thon was a day of working and collaborating to advance Open Research and Open Education initiatives. I was part of a two-person team that designed the event itself as well as the accompanying website, working together to plan what the day would look like and to develop the back end workflow for managing project submissions. I led the UI/UX design and development of the event webpage; my colleague Joe McArthur also was a huge contributor to the site's creation. The code is available on Github.
