Hello
I have done extensive work with Google Analytics API for my employer, and jQuery visualize to build a dashboard with reports about our website. APIs for the other services shouldn't be a problem.
I am very experienced in php and javascript, and I work extensively in wordpress, so building a plugin like this will be easily and effectively done by me.
I can't post references of my work for my employer, but I can show you some code on PMB if you need.
