Summary
|
A Unix/Internet systems administration generalist with over eighteeen
years of experience, in addition to deep specialist skills in areas
relating to mission-critical applications and systems infrastructure
(and scalability thereof), at that nexus where traditional host
administrators don't understand it because it's not a standard host
application and where traditional network administrators don't
understand it because it's not a router, switch, or hub.
I've gotten where I am because I love a good challenge, and there are
always things that needed to be done and I was around to do them.
However, sometimes the best challenges aren't the biggest systems, but
instead scaling smaller systems to handle previously unknown loads, or
coming up with unique and interesting ways to try to solve old
problems.
