Paolo began programming at the age of 9 with a glorious Olivetti M24 (i8086) and GW-BASIC, then he played a bit with Turbo C, Turbo Pascal and Assembly (using the MS-DOS Debug). Quick BASIC and Visual Basic shortly followed, until he learned C++ in College. He tought himself MFC and Windows programming, along with some DHTML and Javascript.
Always attracted by low-level programming and Assembly, he started to appreciate the joys of templates and STL while working for his Master Thesis. For seven months he was playing with airplanes and automatic control at the Unversity of Illinois at Urbana-Champaign, where he first met QNX and embedded systems.
In his job experience he learned Java to develop user interfaces and graphical editors, and re-discovered the Eclipse IDE that he had used in its early versions with the QNX SDK. He also deepened his knowledge of Linux and embedded systems, microcontrollers firmware and embedded voice recognition, while also practicing electronics design.
He graduated in Computer Engineering (Ingegneria informatica) at the University of Pisa, Italy, in December 2003. Currently working for an electronics and robotics company (
www.robotechsrl.com).
He lives in Pisa and in Follonica (GR), Italy.
