proto.io app prototype development

Hello, Looking to hire an expert to help me develop a couple of app prototypes using the [login to view URL] development tool. Candidates must have extensive knowledge and past experience using [login to view URL] to create complete detailed & animated high-fidelity prototypes for mobile tablet and smartphone based applications. Ideal candidates will also have a large amount of experience with Mobile App UI/UX design and, in addition, graphics artist skills are also a large plus but not required (e.g. Sketch experience). I will add the freelancer on as another designer to my projects in my [login to view URL] account and hope to work in tandem with the person to finish two world-class prototypes. One of the projects is targeted at the show/event ticketing business and the other project is completely different and targeted at the Wills/trusts/estate planning business. I will require a nondisclosure agreement to be signed prior to disclosing details about the projects. I am a former software general manager for a multi-billion dollar company and have already created and launched a very successful mobile app business that I recently sold in the live -legal poker industry.
