Rohan Sharma developed a guest-aware navigation bar for the noQ-Frontend repository, focusing on improving the user interface for guest and authenticated users. Using React and JavaScript, he implemented conditional rendering logic to hide the upper navigation bar for users identified as guests, while ensuring it remained visible for authenticated users with higher privileges. This approach reduced UI clutter for new users and streamlined the onboarding process. By leveraging frontend development skills and Git-based version control, Rohan established a maintainable pattern for future role-based UI changes, though the scope of work was limited to a single feature without bug fixes during the period.
