I have being a programmer for the past 25 years of my life. I can program in C++, Java, Python, C#, x86 and x64 assembler. PHP, Ruby, SQL and Javascript. Some Eiffel and some Prolog. I work in a computer games company in US (over the internet) currently as freelancer. So I change work from time to time here and there. I know mostly about computer security, cryptography, compression, some about signal processing and AI. Data structures and algorithms. I studied computer science. I have built several commercial projects and some projects for state owned companies at the Dep of justice.
