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 traking apps, booking apps, social and media apps, taxi and delivery apps ...
So I can help update your Android and IOS mobile apps.
I am sure you will get the perfect project as you want in a timeline and quality.
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.
