Hello,
My name is Povilas and I would be perfect for your project.
I'm Python developer that is certified by Freelancer.com and specializing in custom web platform creation.
For your task I can use Django web framework to create a dashboard were you can controll all your adsense accounts.
I did quick research and fortunatly you can use Google AdSense managment API to manage your adsense accounts.
I have some Ideas and some questions about your project so please contact me now and we can discuss them.
Regards,
Povilas Kudriavcevas
