In March 2026, Tuan Anh worked on the DataDog/integrations-core repository, focusing on enhancing the security of the PostgreSQL integration. He introduced GSSAPI support to the PostgreSQL build process by implementing a minimal, platform-wide configuration change using Dockerfile and DevOps practices. By leveraging builder images with krb5 1.20.1, he ensured compatibility and reduced risk, strengthening authentication without impacting build times or maintenance overhead. This work improved the enterprise readiness of the integration while maintaining a stable API surface. The depth of the contribution lay in its careful balance of security enhancement and operational simplicity across containerized environments.
