Hi. I've read your requirements in detail. I'm an awesome developer who started programming since when I was 12. I'm here to help you and make your idea come ture. Please check my portfolios for my previous works and decide whether I'm good or not. https://www.freelancer.com/u/wangrui8080.html I'm not trying to bragging. But have you seen this on my review? "Wang is a exceptional phone developer both experienced on android and iOS, I'm really happy that I found him, I want to lock this guy forever but am willing to share - if he is bidder on your project , you should feel lucky and forget about hiring anyone else :) He is a perfect combination of being a genius and an extremely hard worker and helped me out till the end right until I was satisfied even with the smallest of detail." Regards
