Worked on enhancing user data visibility in the urlaubsverwaltung/urlaubsverwaltung repository by expanding the API to support retrieval of inactive users. Implemented an active query parameter for the /api/persons endpoint and introduced an Active flag in the PersonDto data model, allowing downstream systems to distinguish between active and inactive users. The approach preserved backward compatibility by maintaining the default behavior of showing only active users unless otherwise specified. Focused on API development and backend improvements using Java and Spring Boot, the work enabled easier reporting and governance while supporting feature parity with integrated systems. No major bug fixes were addressed this period.
