Hello
I am an OS X, iOS and TvOS developer. I've been working with Apple ecosystem for over 6 years, working with most of the frameworks available on these systems. I also have Apple TV available for development and testing.
I am attentive to details and I always consider every little thing, including Apple user interface guidelines for the platform.
Could you give some more specifics what the application is about?
I would be happy to help you with the project and build your TvOS app!
