May I ask: Is this crawler based, I guess?

(because you have some niche jobs/countries on there with some postings :-)

Ya, I spent a month building a pretty complex scraper system that targets ~75-100K companies around the world and manually scrapes their career pages. It was just a fun thing for me to do and it morphed into something useful for others. I had never built a scraping system from the ground up and I really enjoyed it.
