Replace of an existing section from a private portal with new simple code.

We need to rebuild a section from a private portal. we already have a design, I just need you to build it front and backend and reuse some code from other sections of the portal. Please read all: You don't have to design, the site is in REACT with Nodejs and no change with that. The new section it's just a redirection page with graphical links instead of simple HTML links (mobile friendly) and a little posts event page. You will receive all the frontend and backend code via zip file, you need to have your own development environment. The project is very time-sensitive and needs to be done without delay or excuses.
