Hi,
How are you?
I’d like to list my suggestions to make your service app perfect.
1. App development
We should make UI perfect. For this, I am ready with several latest feature such as AutoLayout for iPhone / iPad, Google Material Design for Android.
For the performance of app, it's good to make your app native. For this, I am ready with the latest Xcode and Swift version for iOS and latest version of Android Studio.
2. Backend / APIs development
As a full stack mobile developer, I can also develop backend / APIs. There are several options to build backend / APIs such as AWS and Firebase.
In case of using AWS, we need to develop APIs separately, it takes more effort.
In case of using cloud backend such as Firebase, it's easy to build backend. I think Firebase is good for the backend as Google supports it.
3. For this kind of app, we need to use appropriate location services.
There are several location services and SDKs such as Google Maps SDK, Google Places API, Foursquare / Yelp / Eventbrite APIs. I have strong experience with these services.
With my experience and skills, many miscellaneous ideas I can suggest you while I develop your app.
I am ready to start immediately, work my full time for you.
Looking forward to discussing your project in detail.
Thank you!
