About the Reviewers

Ryan Alford is a .NET software engineer who works from home. Ryan has been a .NET developer for over 7 years, with the majority of his focus being on C#. In his early years, he worked almost exclusively on WinForms and Windows Mobile. He then started working with ASP.Net, AJAX, and Silverlight. In the past few years, as mobile development really started to take off, he took an interest in Xamarin and MonoTouch.

Ryan was able to help convince the management at his employer to use Xamarin for their upcoming enterprise application on iOS, as the company was using .Net and C# in other projects. It was at this point that Ryan was added to the three-person development team to write the new iOS enterprise application.

Ryan has written and released two Android applications: MotoTorch LED and Phase 10 Score Center. MotoTorch LED has more than 500,000 downloads and was one of the first applications on Android that used the camera LEDs as a flashlight.

Today, Ryan is currently rewriting Phase 10 Score Center in Xamarin.Android to ease the development of new features. He is still on his iOS team and continues to add new features to his company's enterprise application.
