I'm a professional software engineer with 30 years of software development experience, (resume available on request). My experience is mostly in digital imaging, and graphics drivers.
I've recently added AdMob Ads to an app that I wrote for another client, I provided that client with a signed release .apk file suitable for posting on Google Play, that displayed an Ad using the client's AdMob ID. I'll be happy to send you a copy of the app if you want. In short - I Can do this project for you and I can do it on-budget and on-time.
Thanks for reading,
Robert Young
