Aug 2, 2016. | By: Lauren Oldja

Last weekend I had an unparalled opportunity to participate in the WWCodeATL hackathon, hosted at ATDC in Tech Square. This was the first such hackathon co-organized by the Tampa, Atlanta, and Charlotte chapters of Women Who Code, and I’ll highlight below some unusual aspects of the event that, as a participant, I think worked really well.
