Seeking good coder to dev game in playstore

Need a programmer to fix a few lines of code, potentially a very short job but if this works out I'll be happy to hire on an ongoing basis. The original developer is no longer able to work on the game and yesterday when the server rebooted a cron is no longer working. It may just need to be restarted is all. The code as I understand it is native Android for the front end and Sinatra in the backend. Programmer should have good skills in Java/Android native, Ruby and MySQL. App uses Google Maps API so experience there is also a plus. All code is hosted on BitBucket. So, to recap, this first project is simply to fix the hourly cron. However, I am also hoping that the coder will want to continue work as this is an ongoing project.
