I am looking for a job. I spent almost 6 years at Puppet / Perforce and I'm an SME at Puppet performance / infrastructure issues.

Adrian is being a bit modest about his troubleshooting skills: he consistently solved many of the hardest config and performance issues that I've seen come up over 10+ years of working with PE. If you need help understanding why software, Puppet or otherwise, does what it does on Linux -- he can help you.
