+export const useUser = () => {
+  const [user, setUser] = useState<undefined | User>(undefined)
+
+  const fetchUser = async () => {
+    const endpoint = `${process.env.NEXT_PUBLIC_USER_SERVICE_URL}api/user/${sessionStorage.getItem('username')}`
+    const response = await fetch(endpoint)
+    return await response.json()
+

+  })
+
+  useEffect(() => {
+    if(!user){
+      fetchUser().then(res => {
