The growing demand for technological solutions has driven the need for systems that streamline the organization, promotion, and attendance of events—particularly within the technology sector. In this context, the development of web applications for workshop management emerges as an efficient alternative to simplify processes, enhance accessibility, and improve user experience. This paper presents the development of TechEventify, a web-based system built on the waterfall model, which integrates technologies such as Laravel, HTML, CSS, Bootstrap, JavaScript, Figma, and MySQL to implement functionalities including user registration, workshop management, ticket purchasing, and an administrative dashboard. The research combined an in-depth literature review with hands-on implementation, including controlled-environment tests to validate both functionality and usability. Throughout development, challenges related to responsiveness, front-end/back-end integration, and logical structuring of features were addressed through technical solutions and continuous refinements. Results indicate that TechEventify meets the proposed requirements and holds potential to support the organization of academic events in controlled contexts. Although tested by a limited user group, the system demonstrates technical feasibility and may serve as a foundation for future enhancements. This work underscores the importance of blending theory and practice in web development education and reaffirms the value of project documentation as a learning tool.
