I started mobile app development from native apps. I used objective-c programming language for iOS and core-java for Android. Later, I used to use Swift language for iOS app. I am familiar with Swift 3/4 and Xcode 9.0. I developed several kinds of mobile apps, such as Dating app, Shopping app, Uber style app, Photo app, Travel app and so on. Especially my main skills are on dating app and shopping app development.
