Yago developed asynchronous operation management features for stackitcloud/stackit-sdk-go and stackitcloud/stackit-cli, focusing on scalable Intake resource workflows. He implemented wait handlers in Go for Intake, IntakeRunner, and IntakeUser, enabling streamlined orchestration of asynchronous tasks and providing usage examples to support developer onboarding. In parallel, Yago introduced a CLI command set for managing Intake Runners, covering creation, deletion, description, listing, and updates, which improved automation and reduced manual polling. His work demonstrated effective API integration and backend development, ensuring feature parity between SDK and CLI, and enhancing reliability and efficiency for developers managing Intake resources across stacks.
