Hi There!
I'm a React Native Developer with 5+ years of experience building applications for Android and IOS and I believe with the experience and skills I have built, I can be the best fit for the role and can help you build Bluetooth driver development and other features as per the requirements.
As this is an existing application, can you please share the back-end code, so it would be easy for me to develop features? Also, do you have a list of what features you want to add?
I checked the mentioned app as well and it looks good, let's discuss further on chat for a better understanding of the work.
My skills include React Native, APIs, Third-party libraries, BLE, HTML, CSS, JavaScript/AJAX, Bootstrap, and more. Additionally, I have extensive experience working with APIs such as Facebook, Twitter, and others so that your website can connect to third-party services without requiring users to register for an account.
I'm confident that my skill set and experience make me the best fit for this project. Please let me know if you have any questions or would like to discuss further how my services could be used to build your website.
Let's have a word soon for a better understanding of the work.
Isha.
