I'm a Linux/Unix system administrator with over a decades experience. I focus on Free Software and OpenSource solutions to problems ranging from operating system provisioning and management to application deployment and scaling strategies.
I'm an ex-software developer and I believe that all good system administrators have some coding experience. It's hard to argue with how useful those skills are, whether used to maintain and add to your own tool chain or for gaining extra insight as to how externally sourced code actually works.
I'm available to conduct technical reviews of books and articles and to write articles and guest posts on my subjects of expertise. I am often involved in organising technical talks and events in London and helping out with conferences further afield.
