I'm also a Debian developer. Here's a page describing some of the packages that I maintain.
I have a public subversion repository of my open-source projects at http://svn.b9.com/.
I sign all my software releases with my GPG key.
As of 2016/03/03, Dr. Rosenberg's domain (b9.com) appears to be for sale.
His new site appears to be http://kpe.io, with his repository converted to git and available at http://git.kpe.io/
