Oh well, if it's Delphi and SQL, the code is probably
easy enough to read. So, in the above-mentioned unlikely
case, it should be possible to find a software engineer
able to familiarize her/himself with the project's details
even without your explanations.

Hmm ... if your knowledge is still valuable, maybe you
can take advantage of that. I'm surprised that you weren't
able to participate in choosing your co-worker. I wouldn't
give away any more information if the whole co-operation
isn't going on your terms. If you made the system run, you
are a strong man and not a loser. The consultant has yet to
prove that he's valuable at all (maybe that's why he's
making these strange suggestions).

It's probably a difficult situation but I think you have
the right to feel stronger and in a much better position.
It's always easy to criticize other people's work in retro-
spect. There's always room for improvement, but given the
resources that you had you probably made some very good
choices.

I think the consultant's words should be evaluated in terms
of how constructive and productive they really are. I guess
having a job called consultant one feels the need to give
advice and find weak points, which may or may not be intended
to actually weaken your position. But your boss needs to be
able to realize which propositions are good and which of them
are useless.

Good luck!
