    C#, C++, and Android software developer with strong algorithmic skills

    Malta - Last active: 3 months ago - Tests: 10 - Portfolio: 2

    In my heart I'm an algorithmic problem solver with a strong background in C# and C++, and an university education that emphasized Computer Graphics, Computer Vision and Scientific Computing. My strong skills in algorithmic and software design moved me to the back-end side of every team I worked in. There I concentrated on object orientation, design patterns, data structures, run time analyses, and efficient test strategies. However, I also enjoy user-centered front-end development (C#/Winforms, Android, C#/ASP.net, PHP, C++/vtk/Paraview, C++/Qt). I'm currently strengthening my presence especially in these areas, with my current focus on ASP.NET and Android.
