GraphQL by itself won't save you time, and might even increase it (it's a huge buy-in). You'd still have to implement the logic for those 4 endpoints, except now in a more complicated system. In contrast, tools like Hasura and Postgraphile can potentially save you time because they generate the GraphQL part for you. Then you only need to handle the authN/authZ parts – in theory, at least.
