The crawler ran fine — as long as a person was attached to it
This customer already ran a custom system watching dozens of Korean shopping sites (Nike, Musinsa, Adidas, and more) in real time. Alerting members about limited-edition drops and restocks faster than competitors, it was the customer's core system. The problem was operations. Shopping sites change their pages constantly, and each time collection quietly comes back empty. Only after someone noticed 'hey, no alerts are coming' would a staffer open the site, find what changed, fix it, check it, and bring it back up — again and again, every time a site changed.
