During my last internship, I conducted a code review. Rajeev and I were the two interns working on the software. He handled the backend, and I managed the front end. I reviewed his code for login and authentication and noticed he used Passport for authentication. Questions arose from both me and our tech lead about its necessity, as it seemed like overkill for our requirements. I suggested using refresh tokens and cookies for a simpler authentication method. I also looked for basic optimization changes. I was responsible for setting up the file structure and ensured that the code was divided into functions, so one file did not hold all the functions. This made it easier to debug and for other developers to pick up the code.
