My Expert Service

In my 18th year of designing and running UNIX infrastructures (initially using Sun OS 4, but for the last 14 years Solaris 2 through 10) from small installations (less than 10 systems) to truly massive infrastructures with thousands of machines (and zones) with hundreds of thousands users. I specialise in deep automation and scripting, and this obviously requires knowledge of applications, protocols, configurations, system validation and services.

Experience & Qualifications

Hands-on, and hands-off, leading by example. actively sharing knowledge, I discuss plans. I take advice. I build consensus. I listen to users, business and technical concerns. I get to the heart of a problem. I resolve issues. I get results.
I am creative and dedicated, demonstrated in two particular ways. Firstly, I am often given the complicated, detailed, delicate tasks others would rather not risk; and secondly, I frequently have already found a solution to problems others are only just becoming aware of. I pride myself on being able to bring wayward projects back on course.
