Hello,
Hope my proposal finds you in the best state!!
I just had a look into your post, I can surely provide you a better solution for your requirement and ready to start immediately, let's get connect for a short discussion I'd love to discuss further.
I’m a professional developer that's been working professionally for over 8 years now, with a specialization in mobile development and designing.
I have successfully delivered Android and iOS application based Online store, Booking application, GPS tracking, Subscription and other relevant application.
In certain I can deliver the details outlined in your description as desired. I've done many projects outside of this line of work, including UI/UX design.
Appreciate if you can quickly reply me so we can discuss more about the job.
Best Regards
