Worked on stabilizing the Recovery Mode user experience for the aws/sagemaker-distribution repository by addressing a critical compatibility issue between the Recovery Mode API and the main SageMaker environment. Used Python and Shell scripting to pin the Python version in Recovery Mode, ensuring environment parity with sagemaker-jupyterlab-extension-common and preventing 404 errors in the JupyterLab UI. Applied containerization and DevOps practices to validate the solution through BYOI testing on a custom image, which reduced manual troubleshooting and support overhead. This work improved extension compatibility, minimized deployment failures, and reinforced a more robust and reliable developer experience within JupyterLab.
