As native mobile development is not my major area of expertise, I still have a lot of experience in the mobile development area and provide my mobile development services.
As the mobile first approach is the de facto default method of development of the new web application there are still a lot of areas where native mobile applications are required.
During my experience, I developed native mobile applications for Windows Phone and iPhone devices. And now with the help of such a platform as Xamarin developing native mobile applications are event easy than ever.
I provide mobile development services using Xamarin as well as mobile-first web development using the Bootstrap framework.
