I'm an independent software engineer. I recently 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:
- JNI Tips (maintained by others for some time)
- SMP Primer for Android
- Android System-Level Graphics Architecture
