Congratulations on your first project, and hackathon entry!
One feedback to give would be to try to get a short domain name as well. We can use simple short slugs for links, but urlshortner-gamma-six.vercel.app is a really long url to type or remember.
P.S. Check out urlshortner-gamma-six.vercel.app/danidre, urlshortner-gamma-six.vercel.app/projectree, and urlshortner-gamma-six.vercel.app/root 😉
