Looking for an app developer -- 2

Hello,

I am looking for someone to continue maintaining and updating my already created app. My old programmer is unfortunately no longer available. You should also have experience in AWS Amazon, because the app is installed on the server.

Here are the data:
Mobile App:
Android -> Jave (Native)
IOS -> Feed
AWS-> Server

please experienced administrators and programmers get in touch. I would also be happy to review references.

Thanks a lot

best regards
