I'm a self-employed software engineer.

In the 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 appear on the official site, including the original versions of JNI Tips, SMP Primer for Android, and Android System-Level Graphics Architecture. I also wrote Grafika and run bigflake.com.
