Employee Management System API

Description

The Employee Management System, EMS, provides all users to use a blog form platform. The blog form allows all users to share information such as job-related articles, personal development resources, and personal reflection on blog posts. Admin can run the payroll application for all employees. Besides, the admin can create, edit, and delete employee accounts information. In addition to that, all users can create and edit their user information.
