Peter Robinson
I'm the least architect of RHEL for Edge in the Red Hat linux engineering team and I'm lucky enough, after actively contributing to Fedora for well over 15 years in my own time.
I'm still actively involved in all parts of the Fedora ARM SIG and get my fingers involved in most pies across the Fedora stack and generally bother people when their package deps bloat too much. I also maintain and co-maintain a few packages here and there that cover a random stuff that interests me and things that people don't want to touch!
Generally I just works on anything that happens to look vaguely interesting, mostly in the small portable device side of things, the cloud, networking, storage stacks or things that help make my day job easier. Hell... what am I talking about I'm interested in just about all of it except perl and java!
