I've been programming since 1985 - starting with Fortran 77, then moving onto assembler, C and C++ in about 1991. I also know enough Java and Python to read code but you probably wouldn't want me writing it.

I've worked in a wide variety of application areas - defense, banking, games and security with the longest stints being in security. I also seem to end up programming devices far too often. This time I'm programming terahertz band body scanners.
