[beh da:d] [es f@h bo:d]
in IPA ASCII transcription.

I was born and grew up in Iran, and moved to Canada in 2003.
Previous, I was a Software Engineer at the Facebook
internationalization team in Seattle.
Before that, Senior Staff Software Engineer at Google,
leading fonts and text rendering, in Mountain View, Toronto, and Waterloo.
Before that I was part of the Red Hat's desktop team,
working from Toronto.
And before I was at FarsiWeb
I am a
enthusiast and developer, and previously worked on the GNOME Project.
My long-term goal since late last century has been to make Persian work great
in computer software, in particular, in
Free Software, though
these days my focus is not limited to Persian anymore.
I'm best known as the author of HarfBuzz,
which makes it possible to read every language of the world on software like
Firefox, Google Chrome, Android, Linux desktop, and elsewhere.
