Hi, sir.
Thanks for your job posting.
I think I can be the right candidate for your project.
Because I have already enough experience in mobile app development.
I suggest React native to your project.
RN is just cross-platform so you can get both iOS and Android apps at the same time.
I have 3+ years of experience in React native.
... ..
You can check my skills during an interview, I think.
I hope to work for you soon.
Best regards.
