I stated my professional programming career at a cable billing company developing back end printing solutions. Since then I have spent much of my career designing and developing large scale (multi-terabyte) data access and analysis platforms, the last 8 years of which have been in the Information Security domain.
I primarily program in C/C++ and lisp-like languages but have years of experience with "scripting" languages such as Python, Perl, etc. and have dabbled (anything less then 3 years of heavy usage) in C#, Ruby, etc.
