Qt

I've created native applications for OSX, Windows and Linux using a variety of languages and compilers. Including ObjectiveC, C++, MFC, C and Python.

Java

Python

Python is my scripting language of choice. I've written network servers, neural networks, image manipulation and 3d image generation tools among other utilities.

Mono

Mono can be used to run both GUI and console based applications on a Linux system. This is often useful if you have ASP.NET web services but no Windows machines to run them on.
