During April 2025, LJH stabilized the Windows Docker build process for the optimize_codegen service in the ML-TANGO/TANGO repository. By identifying and resolving a dependency issue, LJH ensured that Cython was reliably installed during Windows builds, aligning the environment with other platforms and eliminating a persistent blocker. This targeted fix, implemented through updates to the Dockerfile using Dockerfile syntax and DevOps practices, improved cross-platform build consistency and reduced manual intervention. The work focused on enhancing the reliability of the continuous integration pipeline, allowing for smoother development workflows and increased developer velocity by addressing a critical gap in the Windows build process.
