Need to create an internship portal for students and companies to register, sign in, post internships, apply for internships, browse internships and a minimal admin panel, for the entrepreneurship cell I'm college
(cuz the guy who was supposed to do didn't do jack shit in three months, so I have to make a quick one in three days)

Any suggestions on what should I use?
My current options are PHP and Node-Express, but I'm not fixated on either, and the minor details like the templating engine, how to store data, how to implement authentication etc...
