Yohei Yasukawa is a founder of Okinawa.rb (Okinawa Ruby User Group), organizer of CoderDojo Japan (especially Tokyo and Okinawa), and contributor to OpenSource Cafe.

For his enthusiastic contribution to opensource communities, such as translating Rails Tutorial into Japanese and Ruby Hacking Guide into English, he is selected as Super Creator by IPA and nominated as Ruby Prize Award by Ruby Association.

He runs YasuLab, a small distributed company located in Okinawa/Tokyo/California, publishes many products that include Whistle on Android and ScreenX TV, and teaches students what he learns from such projects at Lexues Academy.

And you know, he is very keen to lose his weight for his health; it often fails, though.
