<![CDATA[Infrastructure and technology companies still face challenges in project management because many operational activities are manual, fragmented, and not yet integrated, causing project data management, budget planning, progress monitoring, and reporting to operate inefficiently and delay accurate decision-making. This study aims to design and develop a web-based internal project management system that integrates multi-company master data management, budget planning with multi-addendum support, daily and weekly progress monitoring with S-curve visualization, analytical dashboards, automated PDF reporting, and information distribution through a Telegram Bot. The study applies Design Science Research Methodology (DSRM), which consists of six stages: problem identification and motivation, definition of solution objectives, design and development, demonstration, evaluation, and communication. The system is implemented using Vite, TypeScript, and Tailwind CSS for the frontend, Node.js and Express.js for the backend, and PostgreSQL as the relational database system. Evaluation is conducted through User Acceptance Testing (UAT) involving 29 functional test scenarios across eight module categories, and all categories achieved a 100% success rate. These results indicate that the proposed system improves project monitoring efficiency, maintains reporting consistency, accelerates information delivery to stakeholders, and supports the digitalization of internal project management in an integrated manner. The contribution of this study is the development of an integrated project management system artifact that combines budget management, progress monitoring, project analytics, and information distribution within a single web-based platform to support more structured and measurable internal project management.]]>
