I work in IT since more than 20 years, first at Dassault System and now at Idemia as Software architect. Since the beginning I am enthusiast to use UML for my work.

At beginning with Rational Rose to model sets of classes before coding and now Entreprise Architect to model complex system such as entry/exist system for a whole country.

In the same time, I teach UML at ENSEA (Cergy, France) and I use Papyrus for my teaching.
