Guillaume Alaux developed two core features for the exoscale/cli repository, focusing on deployment orchestration and repository hygiene. He removed the CLI binary from version control, streamlining the repository and improving release management. Guillaume also designed and implemented a Deployment Management API in Go, enabling create, list, update, and delete operations for deployments, as well as management of deployment API keys and logs. His work included updating experimental commands to support assume-role workflows, enhancing governance and security. Throughout the project, Guillaume applied skills in API and backend development, CLI tooling, and version control, demonstrating depth in cloud service integration and workflow automation.
