I built a similar project, for a single industry. Same concept strategically: scraping a bunch of web sites for job listing, aggregating, then providing direct link to the source:
pretty cool, but I think the projects differ a bit in the way they work. Firs 2 Apply only scrapes the list of jobs from the URL that a user saves, so don't have to crawl everything from linkdein.
What did you use to built your scraper? Curious about the tech stack
