Hi,
I may be 3 projects old in this site but I have n experience of developing android apps for more than 3 years, gaining the right experience and knowledge required to build this one.
As far as development strategy, I like to start with the wireframes first, then take it to the final apk stage. For my previous work, do look at my profile, or reach me for any queries you have regarding anything. Last but not the least, the nice reviews are more important to me than the money, so the best work is guaranteed from my side as reflected in my past reviews too.
Thanks
