I Studied Computer Science in University of Salerno, I manage to arrive to the very last exams, but never finished so far... maybe one day.

I have a "Master Breve in Cultura Di Impresa", A master in Enterpise Management from the Bocconi University, Milan.

High School in Salerno, Liceo Scientifico Statale F. Severi.


Languages (non programming): Italian (mother language) and English, very good both written and oral, and currently daily used at work and in life as my primary language (yes, I do have Italian accent, but it's not so strong). I'm learning German, and understand Spanish and Portugues (I can read and understand Portugues better than Spanish, and have short conversations, but I don't do much training so people have to speak very slow with me).

Languages (programming): I Actively program in C, and have knowledge Python and bash scripting. I prefer tools like CMake, Scons and ant over Makefiles and Configure, especially when those tools are intended to be used in a very controlled build environment: I believe is a matter of sanity to use the correct tool for the correct task. I very actively program in Java, in fact my daily job since some years now is to develop the java class library (see expereinces for details), I also have experiences in Midlet and Xlet programming; although J2ME is not any more directly my area of expertise (but I developed quite few thing and a library that, although not maintained, is still quite useful:,  I'm still working on many of the hidden details, as I'm developing for my company various clean room implementations for JSRs (including the CDC and the Personal Basis Profile, as well as all the related JSRs). I also have experiences with OpenGL (2.x and 3.2) and OpenGL ES (1.x and 2.0) and graphics programming concepts in general. I'm interested in functional programming languages like Scala, Haskell and especially Clojure,  which looks very clean and nice, but I honestly don't have much experiences with them yet.

Operating Systems: GNU/Linux and other Unix variants, VxWorks, and other strange OS. At aicas GmbH, I'm responsible and maintainer for the QNX port of our Target Native Layer (including Graphics). I do have passive knowledge of MacOS (will develop more skills here as soon as my new Mac arrives :), very passive knowledge on MS Windows. There are many good expert on this out there, I don't usually develop software on Windows and I'm not really interested in that; although of course at times I need to give up this freedom, I avoid whenever I can, or try to set smart workaroundto help in the time consuming task or using Windows for anything serious. If you are considering to contact me for a job offer, please consider also that Windows is way more expensive than any other OS, and please, don't ask me to use the Windows shell for any reason! :)

Environment: Standard GNU/Unix tools, GCC, Make, vi (But I'm an Emacs user when I don't use NetBeans), ant, Eclipse, NetBeans, CVS, Mercurial, SVN, Bugzilla... you can add more, I use all the standard Unix tools after all, and I am confident in learning new stuff as I need. I have experience of plugin programming for Eclipse and ant (namely, ant tasks).

Team Roles: I did pretty much all the team roles; the two most common are Programmer and Senior Software Engineer, Project Manager for at least two important projects. I have organised task for students and trainees, and I'm Mentoring for the Google Summer Of Code. I am maintainer of the IcedRobot project.

Social and Hobbies: I always dream to be able to maintain a blog about Cell BE and Playstation 3, where to add information about parallel and multiprocessor programming; I really think the future of computing is in the mix of general and special purpose processor, like the Cell BE or the programmable GPUs (nVidia CUDA and OpenCL are the way to go, they should  still make it a bit easier for the average programmer in my opinion). The problem is that I don't have the time I was hoping for this project, so scattered entries are more often than not located on my "real" blog at, where I speak about everything, not just programming (most of the time, it's about life in fact).

I am a very active contributor to the FLOSS universe, as you can read in the Experiences section below. I work in strict contact with the various communities, from Fedora (contributing bug fixes, ideas and spreading the Distribution as much as I can) to specific projects, especially the Java related ones (OpenJDK and GNU Classpath above all). I understand very well the importance of the relationship with the various Communities and even if it's not an official task, is part of my daily job to contribute patches upstream, signal problems, help with find solution, because it's in the best interest of all the parties involved (and it's a lot of fun!).

Life: I'm not married yet, but I love my beautiful, sweet fiancé :)


Worked for various different companies and organisations in small and large project teams. I like to move between projects or switch roles on the same project. This gives me a good overview of the organisation I am working for and the product that has to be delivered. I work on many really large projects, like OpenJDK and GNU Classpath. I'm not scared to learn new things or to touch very difficult and unknown areas. I work well in teams and I usually bring some of the famous Italian style in the place of work :)
