Hi Ricky. I am very happy to answer your question.
I am an Android developer working on a popular app. My favorite part of my every day work process is writing code to implement new features. For mobile development, it is direct and easy to see the results of what we implement on a mobile device. It is very excited for me to see how my work improve the user experience of our app. It is even more excited to see people enjoy using the features I did.
Hope I answered your question.
