Khoa Nguyen focused on strengthening DevOps practices for the st-united/AICP-API repository by building a scalable deployment baseline and improving release reliability. He introduced containerization using Dockerfile and streamlined deployment workflows with Makefile and Helm, enabling faster environment provisioning and reducing manual steps. Khoa also enhanced deployment automation by configuring Kubernetes for PostgreSQL, Redis, and the API via StatefulSet. To protect sensitive deployment configurations, he improved repository hygiene by updating .gitignore and removing tracked environment files. His work, primarily using Shell and YAML, addressed both feature delivery and bug fixes, demonstrating a solid grasp of CI/CD and infrastructure automation fundamentals.
