My expertise is in the implementation of mathematical models by combining the the natural data manipulation powers of R with the pure number crunching capabilities of Fortran. I have over ten years experience developing software solutions in support of scientific research. This experience includes the development and maintenance of commercially available software. Most recently I have joined a university Department of Statistics as a Scientific Programmer developing publically available R implementations of newly developed statistical models whose core algorithms are written in Fortran. If your project requires the speed and accuracy inherent in Fortran, accesible in the more intuitive environment of R, I am confident that I can complete the task quickly and efficiently.
I am familiar with Excel through not only my own scientific endeavors, but also through bookkeeping support of small businesses.
If your project requires the more fundanmental programming approach that I can deliver, I would be happy to provide examples of Fortran code and their R wrappers.
Best Wishes!
