iPhone, Objective-C, Cocoa Touch - Enhancements to App

We have an existing iPhone App that we need some enhancements developed for. The App is called RoamDE and can be downloaded from the App Store from this link: [url removed, login to view]

The code also needs to be improved, to improve error/exception handling, reliability and design issues.

The application uses a persistence framework and downloads and uploads data from a server-side application, so experience working with applications that send and receive data via the internet is essential.

The enhancements we need are:

- Addition of In-App Purchasing (client side only) functionality

- Addition of Push Notification (client side only) functionality

- Login screen, authentication (client side only)

- UI improvements, look & feel: minor tweaks to improve user experience.

We also need an experienced iOS/Objective-C programmer to review the code, and to refactor where necessary, in order to improve the reliability, memory management, error handling, unsafe multithreaded code etc.

We want to find a Freelancer with lots of experience, who we can trust, and we can hopefully work with on a regular basis - there will be lots more projects. People hoping to use this project in order to improve their skills should not bid.

Please provide examples of your work.

Thanks.
