What i like to do.
I am expirienced in FabricJS HTML5 canvas library (also worked with EaselJS, KineticJS and vanillaJS canvas API) WebGL (with ThreeJS library), SVG graphics and RaphaelJS.
Do you need a mobile app for iOS , Android or another platform? I could make HTML5 app packaged through PhoneGap.
I could made Cross-platform application (windows, Linux, MacOS,Android, iOS) with C++/Qt.
