I'm a professional engineer supporting research and commercialisation. Much of my work involves modelling systems, financial and other processes, implementing those models in software, data analysis, data mining, and data analysis algorithm development.
I've developed several software products that have been sold and/or used by others in my organisation in languages including Fortran, Modula-2, C, C++, C#, Java, R, Awk, Perl and Python. Currently, I do most of my work in Python, Java and C#, but I'm also starting to use Scala.
