+Example: users are limited to create only 5 task only per day, if imit reached, return 4xx code to client and ignore the create request.
+#### Backend requirements
+- Write integration tests for this project
+- Make this code DRY

+- Change from using `SQLite` to `Postgres` with `docker-compose`
+#### Frontend requirements
+- Login interface
+- Token management state
+- UI for list/create tasks
