I’m 2E years old (hex). I’ve loved software since I was 10 (dec). I run my own software consultancy specializing in practice, people, process, agility, test driven development, and complex-adaptive systems thinking. I built cyber-dojo.org to promote deliberate practice for software developers. I’ve worked with Accenture, Aviva, Cisco, Ericsson, Friends Provident, HP, Microsoft, Opera, Ordnance Survey, RBS, Reuters, Renault F1, Schlumberger, Tandberg and many many more. If you don’t like my work I won’t invoice you. I’m the ex ECMA TG2 C# convenor. I’m the current ACCU conference chairman. I’ve had some C# books published. On twitter I’m @JonJagger.
