My name is John Tolle. I'm an engineer and statistical consultant in Houston who also does a lot of computer programming.
An area of strong recent interest is model-building with a high level of non-programmer involvement. In practical terms, that means I build lots of spreadsheets...I even I wrote a set of Excel VBA libraries in order to build spreadsheet models like "real" software - that is, as modular, testable, maintainable computer programs. They extended Excel with a true functional programming system with a syntax very close to native Excel formulas. (This was very valuable to my former employer! Please see the Background section of my Stack Overflow Careers profile for more information.)
I also currently work with R, and do some "data-science" programming as needed.
The best way to reach me is by email:
