Muhammad Hassan enhanced the dotCMS/core repository over three months by delivering robust backend features focused on API development and data accessibility. He modernized the Tag API, introducing advanced listing with filtering, pagination, and sorting, as well as import/export capabilities in CSV and JSON formats. Leveraging Java, GraphQL, and Spring Boot, he improved validation, error handling, and documentation across endpoints. Hassan also aligned GraphQL and REST APIs for consistent permission checks and implemented a new User Permissions REST API, complete with integration tests. His work demonstrated depth in backend engineering, emphasizing maintainability, extensibility, and reliable data integration for downstream clients.
