My name is Jethro Villegas—most people call me Jet. I work on the Mozilla Firefox browser. Prior to working on Firefox, I managed Software Engineering for the Adobe Flash Player. Before that, I was the Engineering Manager and Software Architect for the Adobe Flash Professional product. I’ve also worked on a bunch of other software.

This blog is about my personal views on Software Development and other topics that I care about. The views expressed herein are my own and do not necessarily reflect the views of people or companies I work with.

I frequently speak and present at conferences and lectures. If you would like me to speak at your conference or class, please send me a note.
