Here is my Debian QA page which lists the packages that I (co-)maintain.

Debian tools

Apt-get repository

Most of the things that I package are currently in Debian. There are a few packages that are not uploaded to Debian, for some reason or another, or I need a repository as a staging area, or that I've backported.

Release files are signed with my personal public key.

GNUstep packages

Some experimental GNUstep-related packages:

deb http://debian.uhoreg.ca/experimental/gnustep/ ./
deb-src http://debian.uhoreg.ca/experimental/gnustep/ ./
