Chijusha worked on the awslabs/sagemaker-hyperpod-usage-report repository, focusing on infrastructure reliability over a two-month period. They addressed deployment failures by refining AWS CloudFormation resource dependencies, ensuring the ServiceAccountRole was created before the LambdaExecutionRole to improve Lambda deployment stability. In a subsequent update, Chijusha converted the Lambda execution role’s policy from a managed to an inline policy, resolving IAM propagation delays and preventing cross-region role assumption errors. Their work, implemented in YAML and leveraging AWS and IAM expertise, demonstrated a methodical approach to infrastructure as code, resulting in more robust and predictable deployment workflows for SageMaker HyperPod usage reporting.
