Diego Torres Milano has been involved with the Android platform since its inception, by the end of 2007, when he started exploring and researching the platform's possibilities, mainly in the areas of user interfaces, unit and acceptance tests, and Test-driven Development.

This is reflected by a number of articles mainly published on his personal blog (, and his participation as a lecturer in some conferences and courses, such as Mobile Dev Camp 2008 in Amsterdam (Netherlands) and Japan Linux Symposium 2009 (Tokyo), Droidcon London 2009, and Skillsmatter 2009 (London, UK). He has also authored Android training courses delivered to various companies in Europe.

Previously, he was the founder and developer of several open source projects, mainly CULT Universal Linux Thin Project ( and the very successful PXES Universal Linux Thin Client project (that was later acquired by 2X Software, PXES is a Linux-based operating system specialized for thin clients, used by hundreds of thousands of thin clients all over the world. This project has a popularity peak of 35 million hits and 400K downloads from SourceForge in 2005. This project had a dual impact. Big companies in Europe decided to use it because of improved security and efficiency; and organizations, institutions, and schools in some development countries in South America, Africa, and Asia decided to use it because of the minimal hardware requirements, having a huge social impact of providing computers, sometimes recycled ones, to everyone.

Among the other open source projects that he founded are Autoglade, Gnome-tla, and JGlade, and he has contributed to various Linux distributions, such as RedHat, Fedora, and Ubuntu.
