I’m Yuya Ebihara, Software Engineer in Tokyo/Japan. I blog about Software and Games in sometimes English, sometimes Japanese.
My most curious field is exploiting/developing middlewares. I understand it isn’t easy, so always challenging to me. On the other hand, I also like to develop Web application and Mobile(=iOS) application.

Please feel free to contact me. I will respond as soon as possible :octocat:
