The poultry farming industry plays a vital role in meeting the global demand for poultry products. However, traditional farm management practices often face challenges related to data management, resource optimization, and operational efficiency. In response to these challenges, this paper presents the Poultry Farm Management System (PFMS), a web-based application designed to modernize and streamline poultry farm management. PFMS utilizes the Model-View-Controller-Service (MVCS) architecture and a three-tier architectural framework, integrating technologies such as Go (Golang), MongoDB, and React. This paper outlines the methodology, system architecture, software modules, development process, database design, user interface design, implementation details, testing, deployment, security measures, and user training. It also discusses the results, cost- benefit analysis, potential enhancements, and the significant benefits PFMS brings to the poultry farming industry. Key Words: MVCS architecture, three tier architecture, schema design, efficiency, performance
