I am Software Engineering graduate with 5 years' experience of Android app development and I am interested in working on your project. I have read your project description, and would like to talk to you for further details about it. I am currently available to start working immediately, and willing to negotiate both budget and delivery time more to your liking.
I have developed a number of Android apps in the past, and would be happy to show some of those to you as proof of my expertise, if required. Please message me back if interested.
