OK. I am basically a 15 year Linux user, web-stack focused code-wise, but never left the source-based Unix environment and unix-fu. Compiling kernels, configuring HA clusters, low level packet mangling, all good. These days I'm mostly interested in improving development process, emerging kernel features, and systems architecture. Working for a startup remotely right now, very hands on ... everything from speccing hardware and layout to purchase, physical network configuration, system setup & ongoing admin, design of full web stack .. writing all code through to JS .. even UI design. My strength, I would say, lies in breadth of experience and honesty. It took me 15 years to get a job this fantasic though, and that's constant work. When I meet office-dwellers, in a bar, I explain to them: that's longer than a BA, MA, PhD and a few years of work experience combined. And I had to office-dwell, too, once.
