I am an IT software engineer. I am 73, have a masters degree in applied mathematics, and 50 years of IT, begining with Unit-Record and Cobol.
My career has been about 20 years of Banking where I did capacity planning, managing operations, and more. Another 20 years as an ERP architect and consultant, and the remaining years as a software engineer/architect/developer/ for Unix / Linux.
I have been a Linux user since 2004, when I started with Fedora core. Prior to that I was a Unix end-user.
My favourite languages are C and APL, with C++ coming in third.
