Hello, Employer...
I have checked your attached file...
I am an iPhone developer using SWIFT.
I know well about the developing the apps such as Taxi company app, Taxi Booking App, Delivery App and Social Media App…
And I can integrate the services to the app, for example, Google Firebase Service, Google Maps, GPS payment and etc..
I hope to work with you...I can show you my app in appstore...And regarding to my budget.. its not solid..so we can discuss about it..
Best Regards..
Thank you for your reading
