Build scraper for social media activity

I'm looking to build some tools that scrape LinkedIn information. The kinds of things I would like are similar to what may be found at PhantomBuster.com, but that website doesn't provide all the data I need, but it is good to look at for reference.

Data comes from the recent activity page of a LinkedIn profile. An example page is here:
https://www.linkedin.com/in/williamhgates/recent-activity/

And here is a link with a flowchart detailing the specific build-out of how the project will work
