Hi Combinator,
I do have experience with React Native, a robust cross platform framework for building hybrid mobile apps with JavaScript only. In the past few years I built 20+ interactive prototypes, implemented and brought to market 4 mobile apps. My rates are very affordable, a basic info app will cost you less than $1000. My hourly rate for long term is $30/hr (6+ months) and $60/hr for short-term. I work very fast btw.
Send me a message today and I'll be more than happy to share with you references, testimonials and samples of production code. Go to https://murkstom.com/ if you wish to convert your website into webview mobile app, only cost $79 with source code included and no additional branding.
Thanks,
