HRM is a pivotal component of successful business operations, requiring effective management of employees throughout their entire careers. This work concentrates on creating a tool that provides essential functionalities for simpler tracking, organization, and management of human resources. Through the implementation of this web application, users will be able to monitor basic work-related information, such as attendance and working hours, along with additional features like creating and tracking leave and vacation requests, as well as task management. The combination of ReactJS for the user interface and the Firebase platform for the backend ensures a fast, scalable, and reliable platform for human resource management. In conclusion, this web application will provide a versatile tool for streamlining HR processes within organizations, enabling improved personnel management and enhanced communication within the organization.
