Worked on the aws/sagemaker-hyperpod-cli repository to deliver core development space management features, focusing on centralized configuration, template management, and streamlined access provisioning. Leveraged Python, Click, and Kubernetes to build a CLI that enables CRUD operations for development spaces, integrates with the SDK, and supports automated environment setup. Designed and implemented constants modules and utility packages to reduce configuration drift and improve governance. Refactored space access logic for maintainability and future scalability, introducing modular CLI commands for managing access resources. Emphasized unit testing and schema design throughout, resulting in a robust backend foundation for SageMaker Hyperpod development workflows.
