Worked on the awslabs/data-on-eks repository to enhance the Spark-Yunikorn example by delivering targeted documentation improvements focused on execution reliability and setup reproducibility. Addressed command execution issues by updating Bash script instructions, including adding a missing './' prefix and removing a duplicate kubectl command. Introduced automation guidance for replacing S3 bucket placeholders in YAML files, streamlining onboarding and reducing setup errors for developers deploying on AWS EKS. Leveraged skills in documentation and shell scripting, using Markdown and Bash to clarify processes and ensure reproducible deployments. The work contributed to ongoing efforts to improve developer experience in data-on-eks workflows.
