After looking at all the various methods and frameworks for cross-platform mobile development, I decided that Xamarin‘s approach and mature tech was the way to go.
I got a subscription and signed up for the Xamarin University training course. Many late nights doing excellent live training, a visit to the Xamarin Evolve 2014 conference in Atlanta and a tough 150 question 3 hour exam later…I am now officially a ‘Certified Xamarin Mobile Developer’
Oh…and it was not easy! 1 minute 12 secs per question and an 80% pass mark!!
Xamarin certification can be verified at https://university.xamarin.com/certification#verify and found in the Xamarin Certified Developers LinkedIn Group.
