My name is Sonia Hamilton, I live in Sydney Australia. I work in IT and previously I've been at companies like Optus, News Digital and Google.

I'm interested in all things Linux and Open Source, and I also enjoy martial arts - Balintawak Arnis (Filipino stick fighting) and BJJ (Brazilian Jiu Jitsu). After all that training, I do Vinyasa Yoga to stretch out and relax.
