Create an Android & iPhone Application based on Business Networking -- 2

Hello Freelancers, I need to get a mobile application created on both Android and iPhone. The application has a concept around Business Networking in which People can network with each other in their free time like sitting at an airport or a restaurant, etc. Through the application they can create checkin's to let others know their availability. A user profile information will be fetched from social media platforms like Facebook, LinkedIn, etc. Users can chat with each other, so there would chat functionality which would be included. We'll be using any opensource 3rd party chat for this. If you already have worked on any chat API before it would be an added advantage for you. The detailed concept doc is attached below. The designs of the application is ready and will be provided in PSD format from my end. For reference i have attached the designs below. All Web API's and backend Admin Panel needed for the application is already ready. You'll be provided with JSON based web api's, hence you do not have to work on the web part of it, and just have to do the front end integration. The application on both Android and iOS should be a universal app and should work fine on all devices. App would only work on Portrait Mode and Landscape Mode will be locked. You should have experience working with Google Maps API's, LinkedIn and Facebook API's. Do not forget to share your Mobile Apps portfolio with your bid message. Do read the project requirement in detail before placing your bid. Do not ask to change/alter the bid amount in message. Your proposal will straightaway be rejected in that case. You shouldn't be a lone developer and should be a team who can work parallely on both Android and iOS application. Do share links of the application which are live on android and ios stores. The application should be developed with proper coding standards and should be optimized for all type of devices and networks. Size of the application should be kept minimum and only necessary data should be loaded on certain screen. All error cases should be handled well and app should not crash at any point. Add the work "CHECKMATE" before your bid message with your bid message inorder to confirm that you have read the complete project description. Bid with minimum time and cost will be selected.
