Hey,
I'm Vivek and ya this is the first project I'm bidding on. Let's get straight on why you should consider me for this project. I'm a pretty good developer, I code mostly for fun and to make my task easier. I'm been into Android from couple of months and even started Hybrid app development last month. As I can see in your project you just need a basic app with a clickable button to perform certain task. I'm pretty sure that I will be able to complete that on time.
Hoping for a notification of task assigned soon.
