My last eight years have been dedicated to Mobile Application development. In my applications, I have worked with bluetooth, WI-FI, real-time tracking, SQLite database, REST API, Camera Recognition, & many more interesting features. Throughout these years, I have become much skilled in developing full feature apps in both Objective-C and swift (for iOS Apps) and Java & Kotlin for Android apps. Many of the apps I have worked on are very high profile with names you would recognize. Although I can easily develop all aspects of an iOS app & Android app from the networking layer to the front end, I am particularly good at mobile analytics and front-end development. I was a creative person before I became a developer. As such, I have an eye for design. I find that most clients appreciate this. Since I started into this field, I hone my skills every day with the help of professional practice to make the development process faster and qualitative. List of my skills that I will use to bring your project to perfection: โข Java / Kotlin, โข Android SDK; โข Android Jetpack (Room, Navigation, WorkManager, Lifecycle); โข Google AppEngine (Google Cloud Endpoints / Servlets); โข Databases: SQL / Room Persistence, Realm; โข Google API's (Maps, Drive, Tasks, Places); โข Firebase Cloud Messaging(Android / Java Server), Database, Remote Config; โข Google Cloud Storage / Database; โข Material Design; โข REST/JSON/XML; โข Retrofit 2, RxJava, Dagger 2; โข MVVM, MVP; โข OpenCV; โข Gtk3.0 / Vala; โข Git; โข Gradle / Maven If you don't fully understand which features you want. Here, I am to help you. So, What are you waiting for? Let's connect, and I'm just a message away!! :)
