Hey,
I am a practicing Engineer and well versed in designing full stack several hardware as well as their family software. I am willing to do this task pertaining to iPhone, Mobile App Development, Xamarin and Objective C and work for you on a reasonable price and the quality of work would be up to the mark. However, some questions are still needed to be answered from your side if we interact.
I am a quick learner so you can start me on any project with confidence that I will learn any topics/areas quickly and deliver professional software that suits your needs.
Thanks,
Salman.
