Front-End or Fullstack?

I'm working on a project for my education, it's a web application that consists of a freelance platform, I'm currently working with Angular but I'm still a beginner at web development so I'm wondering if Angular is enough to create a complete and consistent web app or should I integrate a back-end framework as well? the problem is that I only have about 2 months and a half to complete it and I don't know if that is enough for me to master it. And thanks for your attention.
