iOS and Android developer needed for bug fixing and improvements for existing project -- 2

I'm looking for someone to take over my existing app project (a social quiz app for couples). It's barely launched (just got into Play Store and App Store) - and the current developers are moving on to greener pastures (moving abroad and getting hired). So I have to find someone else to do the iOS (Swift) and Android parts moving forward. You should have some proper time on your hands - at least for the next few months - to be able to quickly fix bugs and crashes soon after they're reported. Fast bug fixing is very crucial. Besides that, I have quite a few improvements and new features to be made. You should be active on Skype and be able to use Jira for issue and work tracking - and be able to always write a line or two in each issue about what was done (what was changed e.g. if it's a bug fix). You have to write sleek, simple and high quality code and do proper testing of your own work before delivering it (on at least one physical device). Not testing properly (resulting in issue reopenings and waste of time for both of us) is a dealbreaker. Current code is written per Android and Apple guidelines and should be continued to do so. For the next weeks, at least, I'm thinking there's enough work for 15-30 hours per week depending on if you can do both Android and iOS or just one of them. For this project, fast and efficient bug fixing and good Skype communication is very important. Also, I'm looking for a high quality long term relationship as I'm not interested in changing developers again anytime soon. A little about the app: It's social quiz game for couples where users can signup with and without Facebook and then connect to each other and answer questions about sexual preferences - and then guess what each other answered. The app counts scores and winners get to select a prize. We use HeyZap for ad mediation (videos and static interstitials), have our own custom API with documentation, API-log and user administration. The app also has 2 different IAPs (2 new IAP features should be created later). It also has a chat area and utilizes push notifications. *And just to be clear... The apps are already up and running. What I'm looking for is someone to take over the development of the app going forward (bug fixing, improvements and new features). **Signing an NDA is necessary before you start working.
