Developer to Fix Bugs in Slot Casino Game

I have a slot casino source code developed in Cocos2d that has crashing problems. I am seeking an experienced developer to fix the bugs in this code. If a developer is able to fix the bugs there will be more work available expanding the features of the app. The app must run on Android and iOS.

Must have:
- Extensive experience with Cocos 2D, C++ and Objective-c
- Extensive game development experience
- Be able to provide a portfolio of games previously worked on
- Experience developing games for iOS and Android
- Ability to upload compiled codes to app stores

Desired experience:
- Previous development of casino games
- Previous experience with slot machine games
