Hi,
I am an expert who is working with not only iOS native app development but also web service programming with backend as well, having 7+ years experiences.
I have read your requirements, and have great interest to your job as I have so much experiences in any kinds of mobile app development like social networking, gps tracking, photo editing&sharing, QRCode scanning and so on.
I have rich experience with iOS SDK and software architecture using Obj-C and Swift language so I can guarantee quality of my code.
Here are my working styles.
1) I always keep client's requirements as rule.
2) I can be available anytime if you want.
3) I am able to send daily report or commit source code to BB or Github everyday.
4) I will absolutely keep deadline with perfect features.
I am sure I can implement all the feature as you want perfectly on time.
Looking forward to work with you.
Thanks.
