Business-savvy iOS app developer needed

Hello - thanks you for taking a look at this opportunity. Parking in all cities globally has a high pain point and high use frequency and is therefore perfect for disruption on the both the demand and supply side. This is where i believe we may have discovered the secret sauce (and the data) to provide a valuable solution to all the stakeholders who have an interest in parking. Welcome to "xxx" - a unique SOCIAL PARKING app that exchanges information and rewards about parking availability between motorists, residents and local businesses. We already have some open source code for the rails api. With further customisation/development we need to deploy to a server (Heroku), replace the API_URL variable in iOS with the one of our api, then setup a [login to view URL] account for payment and exchange of rewards. Then link a facebook app to our project (use facebook login), and then it's ready to start. We don't need mixpanel / heap / appsee / taplytics to start it up. I am looking for an app developer to get into a business partnership. You make the app i market it and we share the profit 50/50. You need the following skills; • Experience of Objective-C, development for iOS and Xcode • Experience of development best practices, software principles and code design concepts • Knowledge of common design patterns, frameworks and libraries for iOS • A passion for code quality and craftsmanship • Experience of working with integration of 3rd APIs • Interest in UI development • Working in an Agile team using Git / DVCS • Some practical experience with TDD and / or BDD, for iOS or other platforms would be nice • Some experience with API design and Ruby • Experienced / interested in functional programming • Active Github account / open source contributions • Experience of additional platforms, such as Android or mobile web
