I'm senior software engineer at Red Hat and maintain some RPM packages such as vim, ed and some minor other stuff. I'm a packaging Sponsor and sometimes help review and sponsor new packagers.
I used to spend most of my time working as the secondary arch maintainer of Fedora for PowerPC and s390x. Right now I'm in the Modularity team and work on the definition and implementation of modules.
To make life as a secondary arch maintainer a little easier, I've written patches for koji-shadow and some kind of dashboard for the PPC koji hub
koji tricks, i.e. with koji-shadow
