Currently young computer engineer just out of school. I worked and still work with many technologies like C++, Qt, C#, Java, Python, JavaScript, AngularJS, Android, Xamarin...
Daily working with StackOverflow, I can say this is my main source of computer information (after original manuals of course !).
Still learn many things every day and try to improve my Stackoverflow experience by commenting, upvoting, answering when I can.
