How to automate content updates from external job-notification sites in a Frappe/ERPNext deployment?

Hello everyone,
I regularly notice websites that publish government exam results and job notifications (for example: rojgar–result and I’m wondering how to build or configure a system using Frappe Framework / ERPNext to handle this type of workflow.

Here are some specific questions I have:

  1. What’s the best approach to pull in data (such as exam result entries or job notifications) from external sites via API or scraping into Frappe/ERPNext?

  2. Once the data is in Frappe, how can one trigger notifications or alerts (email/web-portal) when a new result or job update is added?

  3. Are there performance or architectural considerations to keep in mind if the site receives lots of updates per day and many users are accessing the data?

Would love to hear from anyone who has done something similar, or can share best practices for this kind of content-update automation in Frappe/ERPNext.
