What do you say your profession is

[billybiro]

Work at a bank? Amber screen or dark screen background with either green or white letters?

Software Auteur

Or when I'm feeling less pretentious:

Code Monkey

[NotAllThere]

IT consultant or Informatikberater.

[Platypus]

In social situations I normally say that I talk bulltulip for a living. If I need to be polite I say I work in IT.

On a form, a put something that the reader/form processor will understand, depending on context.

Tip: never put 'manager' I read some time ago that it's a very bad answer on credit application forms since managers tend to have poor job security.

Otherwise it's whatever people want to hear.

[TheFaQQer]

Director. Managing Director. IT Consultant.

One of those, depending on who is asking.

"IT Contractor" usually, or maybe "nipple tweaker"

When asked for it when filling out a form?
Director (assuming you're Ltd company director) or what you actually do ie Project manager, software developer, BA, etc
