Ebenezer Edelman is a British computer programmer currently living in South Africa. He has an eclectic and diverse set of interests ranging from technology, engineering, and science to literature, photography, videography, and music. His hobbies include playing the piano, designing rocket engines, and occasionally a game of chess.

He started game development by learning C from the manual of a C compiler and developing simple text-based games. Then, after getting to grips with C++ and the DirectX SDK, he attempted to develop a 3D physics sandbox game, which never got past the beta stage. After that, he learned C# and the XNA framework and made several 2D games before deciding to get involved in mobile game development. He did this using Java and the LibGDX framework, which he used to get some of his old 2D games to Android. He is constantly looking to broaden his knowledge, and he now uses Research In Motion's open source C++ game engine gameplay3d.

In addition, he has experience of Windows Forms (C#), the GTK+ toolkit (Vala), the Qt toolkit (C++), the Android SDK (Java), as well as the x86 Assembly language, Python, PHP, JavaScript, and HTML/CSS.

His personal website and blog is located at http://EbenezerEdelman.tk/, and he is on Twitter (@EbenezerEdelman) and Google Plus (+EbenezerEdelman).
