Dokyu Han developed core authentication and authorization features for the 02-Solutions/Monarca_Backend repository, focusing on secure user management and scalable access control. Over two months, Dokyu implemented JWT-based authentication with password hashing, migrating the system from role-based to permission-based (ABAC) authorization for finer-grained control. The work included aligning the database schema, updating guards and decorators, and enhancing developer visibility into authorization decisions. Dokyu also improved end-to-end test coverage for authentication and reservation flows, modernized project documentation, and fixed a key login/logout regression. The project leveraged TypeScript, NestJS, and Docker, demonstrating depth in backend engineering and maintainability.
