I'm a software engineer at a small startup.
In the recent past I worked for Google, on the Android platform (2005-2014). I spent five years working on Dalvik (2006-2011), and two on system-level graphics (2012-2014).
I've written a few documents for Android developers that now appear on the official site, including JNI Tips (which has since been updated a few times), SMP Primer for Android, and Android System-Level Graphics Architecture. I also wrote Grafika and run bigflake.com.
