Ajang Gunawan contributed to the aws/aws-toolkit-vscode repository, focusing on improving SageMaker integration and remote IDE workflows over a three-month period. He enhanced connection stability by refining handshake logic and robustly decoding workspace URLs and tokens using TypeScript and the AWS SDK. Ajang introduced unique workspace identifiers to prevent duplicate SageMaker windows and restored reliable presigned URL handling through hostname resolution. He also delivered features for idle activity monitoring and expanded SSH configuration, refactoring connection logic to reduce complexity and prevent disruptive user experiences. His work included comprehensive unit testing and cross-platform validation, demonstrating depth in full stack and VSCode extension development.

January 2026: Delivered reliability improvements for SageMaker workspace connections in the aws/aws-toolkit-vscode extension. Implemented a unique workspace identifier to prevent duplicate external windows when connecting to the same SageMaker workspace, and restored stable presigned URL handling by reverting changes and using hostname resolution via the EKS cluster attribute. Updated unit tests and validated locally with the new VSIX, supporting release readiness and compliance with contribution guidelines.
