Cloud hosted simple web tool scraping a few websites for data and collecting all in single front end.
1) scrape a company database for names of companies (free access but they make it difficult for scrapers)
2) scrape Linkedin Sales Navigator for employee data of companies from 1st step (also difficult for scrapers, but Linkedin Sales Navigator should be easier than regular Linkedin)
3) pull additional data about the companies from another database with open API (docs available)
4) present all data in simple spreadsheet-like front end
