Android and IOS platform expert needed. - repost

Hello: I need an Android and IOS specialist. Please DO NOT bid on this job if you are not an experienced developer. I am not looking for someone who is just starting out. You must be able to work on both Android and IOS platforms or have another developer who can work with you for a platform that you don't know about. I need my apps updated and I have many products and services that need to be built. I am looking for some one for long term as this work will continue for months to come. Right now I just need my apps updated which have not been updated since 2011. The apps should work on all current devices. Also, several components are data base driven so you must know server coding as well. Thanks.
