Hello ✋✋✋!
I am an Android and IOS, Web(PHP, Node, Firebase ...) Backend Expert and have full experience over 5 years.
Last time I built several GPS tracking apps, booking apps, social and media apps, taxi and delivery apps ...
So I can discuss to improve your mobile app's features and functions.
If you award me the project I'd be very happy to discuss this further and get started for you as soon as possible.
Best regards.
