Developed and integrated AWS Batch Quota Management into the SageMaker Python SDK repository, enabling quota-based job submission and dynamic job prioritization for large-scale training workflows. Enhanced the submission API and updated the TrainingQueue integration to respect quota allocations, while providing a new example notebook to demonstrate quota management in practice. Addressed reliability by ensuring AWS Batch integration test resources are uniquely named per test run, eliminating conflicts during concurrent testing. Leveraged Python, AWS SDK, and batch processing expertise to expand SDK capabilities, improve cost control, and increase CI stability, delivering both feature enhancements and robust testing improvements within a single release.
