He was formerly a senior operations engineer at global telco Verizon, designing resilient, high-performance infrastructures for major corporations such as Ford, McDonald's, and Bank of America. He is now an independent consultant, working closely with selected clients to deliver web-scale performance and enterprise-grade resilience on a startup budget.He likes writing books, especially about Puppet (Puppet 2.7 Cookbook and Puppet 3 Cookbook are available from Packt as well). It seems that at least some people enjoy reading them, or maybe they just like the pictures. He also provides training and coaching on Puppet and DevOps, which, it turns out, is far harder than simply doing the work himself.Off the clock, he is a medal-winning competitive rifle and pistol shooter and a decidedly uncompetitive piano player. He lives in a small cottage in Cornwall, England and believes, like Cicero, that if you have a garden and a library, then you have everything you need.You may like to follow him on Twitter at @bitfield.
