Worked on the pulumi/pulumi-java repository to address a reliability issue in the Pulumi Java SDK, focusing on command line interface argument handling and SDK development using Java. Delivered a targeted bug fix that corrected the preview plan save flag, changing the argument from --plan to --save-plan to ensure preview plans are properly saved to disk. This adjustment improved the reproducibility of infrastructure previews, particularly in CI/CD workflows, by enabling consistent plan file generation. The work demonstrated attention to detail in CLI argument parsing and contributed to more reliable automation pipelines, while minimizing risk through a focused, repository-specific change.
