Markus Kohn completed a comprehensive refactor of the ticketing subsystem in the Lan2Play/eventula-manager repository, focusing on improving clarity and maintainability. He systematically renamed core models and tables, such as EventParticipant to Ticket, EventTicket to TicketType, and EventTicketGroup to TicketGroup, updating all related references, relationships, factories, and migrations. Using PHP and Laravel Eloquent, Markus ensured data integrity throughout the process while simplifying the domain model for future development. His work in database schema management and refactoring reduced maintenance overhead and streamlined onboarding, laying a foundation for safer, faster feature delivery within the ticketing system’s evolving architecture.
