Worked on the ovh/shai repository to enhance installation control and version management for the SHAI CLI tool. Developed a SHAI_RELEASE-driven installation process, enabling users to specify and install particular release versions, which improved deployment reproducibility and allowed for precise version pinning. Introduced a --version flag to the CLI, leveraging Rust and Cargo metadata to provide clear visibility into installed versions. Addressed a key installer bug by ensuring POSIX compliance in the shell script, correcting echo usage and parameter handling for robust, error-resistant deployments. Demonstrated expertise in Rust, shell scripting, CI/CD workflows, and DevOps best practices throughout the project.
