This is us, it's me Paul Sterling. I've been working with Umbraco since 2006, founded Motus Connect in 2007, joined Umbraco HQ in 2010, and now (in 2017) I am back helping other Umbraco users full-time. How nice is that?
I'm an Umbraco Certified Master Developer and, even more than that, I have developed the current Umbraco Masterclasses along with my colleagues at Umbraco HQ. Since I started delivering Umbraco Masterclasses I have trained more than 400 Umbraco Certified Developers - maybe you were one of them.
