The importance of an efficient and secure back office is fundamental to the success of modern businesses. A well-designed back office not only streamlines internal processes but also reduces operational bottlenecks, supporting smoother and more reliable workflows across departments. In a rapidly evolving market environment, optimizing the management of critical areas such as finance, human resources, and compliance becomes essential. This thesis aims to design and implement a comprehensive back office system that employs state-of-the-art technologies for both backend and frontend development. By leveraging modern tools and methodologies, the project seeks to enhance operational efficiency and user experience, ultimately improving overall business performance.
