Professionally, a freelance IT consultant and writer, mainly on technology matters for various publications.
Personally - well, a not-very-comprehensive list of characteristics might read, alphabetically: Atheist, biker, biologist, SF fan, skeptic, vegetarian.
White, monogamous, heterosexual, male Englishman; unpierced, untattooed, doesn't use tobacco or caffeine.
Not as dull as the above may sound.
