Fjob backend

FJob is a fullstack application (main technologies: Django Rest Framework, Nextjs, Selenium). FJob, by collecting job offers from many job portals (currently only JustJoinIT, but there are already scripts ready to collect data from: olx, Pracujpl, nofluffjobs, Pracujpl) and enabling companies to post their own job offers will allow you to easily search for job offers.

!Info!

The project has undergone significant changes in terms of code architecture. Initially, all application logic resided in views. Currently, thanks to the use of Repository Pattern and Service Layer, views have been significantly improved. Not all views use this architecture, I left some of them unchanged because they use abstract classes from DRF, so there is practically no business logic in them.

---

The application is no longer available in the demo version, I don't have money to maintain it with this architecture :(

System Architecture

Fjob consists of 3 repositories:

• Backend https://github.com/DEENUU1/fjob_backend
• Frontend (current)
• Scrapers https://github.com/DEENUU1/fjob_scrapers

Features

!NEW! I started refactoring the current application and moved a large part of the code initially saved in views to the service layer using the repository pattern. Some views have remained unchanged due to, for example, their simplicity related to the use of Django
