The growing demand for efficient, secure, and eco-friendly event management systems has accelerated the shift from manual ticketing methods to digital platforms. This paper presents QVent, a centralized event management and ticketing solution designed to connect event organizers, administrators, and participants through a single web-based system. QVent enables organizers to register, create, and manage events ranging from cultural fests to hackathons, while attendees can browse, register, and purchase digital QR-based tickets. Each ticket is uniquely generated, ensuring secure and contactless entry verification. Built using Java, Spring Boot, PostgreSQL, and RESTful APIs, QVent aims to streamline participation, minimize fraud, and enhance user experience. The system follows an Agile development model and supports modular growth for future improvements such as AI-driven recommendations, dynamic ticket pricing, hybrid event support, and mobile application integration. This paper discusses the problem background, related work, methodology, system requirements, architecture, implementation approach, results, limitations, and future scope of QVent. It also includes a declaration of AI tool assistance used during manuscript preparation.
