Hello, we are looking for a Senior Fullstack Developer to cooperate in the implementation of a web portal with login and registration functionalities (Facebook, google, standard registration after completing the form). The website should also allow you to complete data and add pdf files for a specific user. Everything should be stored in the database. The site should be able to log in for 3 types of users for whom different internal panels will be visible. The site should be responsive up to the version displayed on tablets. A mobile version is not necessary. More details at the meeting.
