Hey, I hope you are doing well!
I can help you to build an application for Android & IOS both platforms as I am having more than 7+ years of experience as an IONIC developer this is not a complex task for me but I would like to know from where did you buy the source code? and also is there any other task apart from this?
I have recently completed this kind of project on this platform only, you can check it in the review section.
Let's connect to discuss your requirement!
Thank You.
