thats great to hear that, i am at the moment creating myself a humanoid based on ROS at the initial level and working with you will help me to sharpen my knowledge on machine learning, well thats a later story.
we are working with REACT NATIVE since a year and we can help you to build the app on it, you can check that we are already working on REACT NATIVE for one of our client here https://www.freelancer.com/projects/Mobile-Phone/React-Native-App-Development/
Note in order to bid you must agree to the following terms
1. Assign your IP for the work to our company
=> no issue with that, from a day one we will push the code to git so all code will be yours
2. Use Github
=> yes that no issue with it
3. Use our Slack channel daily
=> yes that is fine.
Looking forward to hear from you and ready to discuss further!
Thanks,
