I have 6 years of experience in mobile application development. Most of the time I developed the app in Java. I have done many projects in the mobile app. For the API connection, I use the retrofit java library. I know about the social login and make the API documents for the app. I have worked on the Google ads and facebook ads integrate into the application of the app. According to mobile technology, I am developing a mobile application in new technology like KOTLIN and JAVA. Kotlin is a new technology in mobile app development. It is very fast technology which saves the development time and app design is looking too much attractive in this technology. As well as the technology I looking at the design pattern of the application architecture. When we focus on the Mobile UI part as well as our backend part should be strong. So I know the API integration and connect with the third party library and Also know about the Google maps. I have done most of the project on Maps like track the vehicle and attach the custom marker on the google map. I know the push notification work in the app development. I follow the two types of design patterns to make a dynamic app. MVP and MVVM these patterns help to make the dynamic app with integrating the API and library. I am making the application design according to different sizes of mobile screens and tablets. Most of the code I make my custom code to make development easy and fast. I follow all concept of Java and Kotlin. There is Object-oriented programming language is the big concept of the programming. Professional developers are using the concept of the programming language. I also work on website development. I know about website design and development. Designs are based on the Html and CSS code. for the dynamic, we use other languages like PHP.JSP etc.
