what does "pieguy" mean?

I have seen some questions which have the tag “pieguy” .But I can not find the meaning of it in the dictionary.Can anybody tell me what does “pieguy” mean?

Eheheh!!

pieguy is the alias of one of the problem setters here and also a very famous one on Codeforces :slight_smile:

It’s the alias of David Stolp, which, last time I checked was an Enginner at MemSQL :slight_smile:
