I have been a data scientist/miner for over a decade, and a developer and IT sec pro before that. I use R, Python, C/C++, Lisp, SQL Server, Azure Machine Learning, AWS, PHP and Drupal. I work for my consulting company Project Botticelli Ltd. I use a Mac, I suffer Windows, I happily run my business on FreeBSD, and I fondly remember the ICL1905/Odra mainframes. I stopped using Pascal, SNOBOL4, Prolog, and PLAN4 a good while ago, and I no longer adore VB, Basic or Fortran. In my non-IT life I make silver-gelatin photographs, see rafal.net.
