Hi all, I'm looking for a developer with experience of working with Cordova with the Ionic Framework - in particular someone with experience of integrating plug-ins that provide different functionality. We currently are developing an app that already has various functionality, however we require developers to be able to finish off certain parts: e.g. implementing Push Notifications, and implementing ability to select images from device and upload them to a server. So, for example, we already have functionality set up where a user can send and receive messages, and we now need to finish this off so a user can also receive Push Notification when they get a message but the app is closed. We are thinking this would be an ongoing project, we are trying to develop a long-term relationship with a reliable developer who can add lots of plug-ins in to the app for us going forward. Thanks

Dear Upwork Family, I am looking for a talented Unity (App) Developer who can complete our simple Stack App from pre-existing code that we've already completed. Our previous Unity programmer has gone on a personal holiday, so we need another programmer to help us stay on deadline by completing this app for us now. The app code is about 90% complete. So, after you review the code, you will be working directly with our designer to wrap up the remaining elements of this simple game, with Ads implemented etc. --> Then you will need to publish the game to both the Google Play and Apple app stores in our account. The App Itself, you're in essence completing an almost exact replica of the known "Stack" game just done with our own twist put on it. Here's the Stack game for your reference: https://itunes.apple.com/us/app/stack/id1080487957?mt=8 If you're available and interested in this project, 1.) Please respond with your availability and a few words about your experience creating apps with Unity and 2.) Your experience publishing games to the Google and Apple App store(s). ***IMPORTANT: You must be a great communicator and you must work alone - Please confirm these two important points in your reply.*** Thank you and I look forward to working with you! :) Khalfani
