Who I am

My name is Radu Motisan, and I was born in '82. I am trained as a software engineer, with a master degree in Computer Science from West University of Timisoara received back in 2007. My university years brought me in the beautiful city of Timisoara, where I live today, together with my wife.
I work as a freelancer and I have a wide interest for technology. Besides what my school years taught me (mostly mathematics and informatics), I also have knowledge of electronics, physics and chemistry.

Why I'm on Projects

To summarise everything I'm here because I like technology and the potential of new, innovative things.
