Thank you for your initial contribution to our project! 🎉
I've provided some feedback below, along with explanations to help guide your learning process.

Please take a moment to review these comments. Once you've addressed them, remember to run the command yarn make-pretty before your final submission. This step is crucial to ensure that your code passes the Continuous Integration (CI) checks.

I've also made a small update directly in your branch. The change involves the backend, where I've enabled support for identifiers with a length of 1. Previously, the minimum length was set to 2, which was causing API validation errors specific to your campus's needs.

Looking forward to seeing your revised submission! 💜
