Hello
I just read the requirement carefully.
As I am a Mobile and IOS developer with over 6 years of experience, I have deep knowledge of Swift, Flutter, React Native, and so on.
I have built a similar Bluetooth app with React Native for another customer in the past.
I am available during business hours Monday to Friday and I can work full time(40 hours/week).
I want to discuss the details via private chat.
Waiting for your reply.
Best regards.
