During December 2024, JK focused on improving the reliability of credential export processes in the aws-samples/eks-workshop-v2 repository. Addressing a bug in OpenSearch setup, JK refactored the shell scripting logic for AWS Systems Manager parameter retrieval by removing unnecessary tr usage and adopting jq -r for raw string output. This adjustment ensured that credentials were exported accurately, preventing unintended character stripping and reducing the risk of credential corruption during deployment. JK also updated the project documentation to reflect these changes. The work demonstrated practical application of Bash, AWS CLI, and documentation skills, delivering a targeted and robust engineering solution.
