I need a developer to build my Minimum Viable Product / Demo for software company

I am looking for a remote Programmer who can build a software prototype based on my own screen designs and concepts. I need someone who is available, with experience in building MVP's.
HTML, Javascript, React Native background preferred.

After our demo is built, this product will be sold via direct sales to generate customer feedback and find market fit for presales.

Looking for a committed person who wont disappear in the future.
