During June 2025, Tuan Vu Thanh focused on stabilizing CI/CD pipelines across the ncc-erp-workflow-w2-ui, ncc-erp-workflow-w2, and ncc-erp-ams repositories. He addressed deployment reliability by implementing targeted runner environments, pre-deployment cleanup routines, and explicit branch targeting, all using YAML and GitHub Actions. His work included migrating workflows to dedicated development runners and the AMS dev runner, which resolved environment-related failures and improved deployment consistency. By fixing three critical bugs, Tuan enhanced reproducibility and reduced misdeployments, demonstrating a strong grasp of DevOps practices and CI/CD automation. The work reflects depth in pipeline reliability and environment management.
