I am a full-stack systems thinker who is comfortable going from modifying kernel code to hacking modern web pages in the same afternoon.

Over the course of my career, I've spent equal amounts of time doing systems administration and programming. This has led me naturally towards a systems approach to both disciplines. It is often referred to as being full-stack, which I think describes my abilities quite well. Where the stack is built from Linux, open source, and commodity components, I have a lot of breadth of knowledge to go with the depth.

My professional tenets in a nutshell:

• the right thing must be easiest thing to do
• always have a plan B; plan C is often advisable as well
• get it running, then fine-tune it
• scalable designs grow with the business
• scalability has three dimensions: horizontal, vertical, and human
• policy problems are rarely solvable with technology
• pithy quotes lack context
