Hello, I have gone through with the project description and understood your requirements. I am skilled in push Notification, RESTful API (MySQL & PHP), Geolocation, Google Maps API, JSON, Firebase (online data storage) and AdMob integration. I have made Kids Monitoring System, A1 German Language, Restaurant Application and Real-time chat applications (you can check my portfolio).
I can START RIGHT AWAY and would be happy to answer any questions you might have. Looking forward to hear from you.
Best wishes,
Abdul Rehman Anis Ghazi
