I'm a brazilian developer, working and living in Japan since 2003. I speak portuguese(native), japanese(fluent) and english(Intermediary level, TOEIC -> 910).

I develop business apps most of the time, experienced in Android and iOS platforms using native language (Java and Objective-C), Titanium and Xamarin. I also have server-side experience using PHP, node.js, Java Tomcat, Scala and also made some projects using Arduino, Konashi, SensorTag, and Kinect. I use python for scripting. My main project uses Bluetooth communication between smartphone and MFI devices like Car Navigators.

Also studied AutoCad and Solidworks few years ago, but I'm not sure if I remember something ...
