List all user accounts in the entire social network (due to the number of users are still small, I did not develop search user function)

Other functions:

Due to limited storage space, client app compresses the uploaded image to the maximum of 250px (width or height)
User avatar is created by hashing user id and convert that hash code into a hexagonal image
Authentication and authorization use JWT
Responsive frontend for desktop and mobile devices
