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?


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:
