I'm Jon Jagger, a UK software consultant.
You can hire me! My email address is [jon AT jaggersoft DOT com]
I help teams improve their effectiveness at collaboratively developing software. I built cyber-dojo to promote deliberate practice for software developers.
If you don't like my work, I won't invoice you.
I attended the excellent Agile .NET 2011 conference in Ghent, Belgium this week. Jason Gorman pulled out at the last minute and Erik asked me if I'd step in and do the keynote. I said yes of course and prepared this on the train+plane there.
