Scraping data from LinkedIn has become extremely difficult in the last few years – especially at scale. Tools like Phantombuster can help scrape around 100 profiles a day - but how can you scale up to thousands a day for your ambitious project?

Using Python language, in 2018, I built the "one of its kind" system for large-volume LinkedIn scraping.
