During November 2025, Nhat Thanh developed an access control enhancement for the associatedG/pmso-service repository, focusing on order management workflows. He expanded the Order Status policy for IMPORTING_AND_EXPORTING to include LOGISTIC_MANAGER and PRODUCTION_STAFF roles, ensuring proper segregation of duties and supporting scalable operations. Working primarily in Python, he applied backend development and access control expertise to strengthen security and improve compliance auditing. The implementation involved policy extension and thorough verification, with no major bugs reported. This work laid a solid foundation for future features, addressing the need for reliable, auditable access control in complex import and export order processes.
