Globetrotter, you must really compose your posts more carefully, and
take more time in proofreading them before you post (click 'Preview'
below the message box first, not 'Post').
I'm not sure what you are enquiring about, but the nonfinite clause
after having done =
after doing
in most contexts. The former stresses the recent completion of
the event, and yes, connects it more to the subsequent action as a
consequence or other related event. It is not the perfect aspect,
since it is nonfinite, and just expresses general completion. A
'past perfect' form does not exist.
