During February 2025, this developer enhanced the utfpr/hcf-api and utfpr/hcf-painel repositories by focusing on both security and data model improvements. They implemented Docker container security hardening by introducing a dedicated non-root user and adjusting file ownership, reducing potential attack surfaces. In parallel, they expanded the taxonomy model by adding a Kingdom entity, updating the Tombo model, and integrating these changes into the user interface for taxonomy management. Their work utilized JavaScript, Docker, and React, emphasizing robust database design and frontend development. These efforts improved data integrity, security, and user-facing taxonomy governance without introducing any new bugs.
