Worked on the temporalio/samples-typescript repository to deliver performance and reliability improvements focused on modernizing the codebase. Upgraded project dependencies, including the TypeScript SDK and OpenTelemetry plugins, to version 1.15.0, ensuring compatibility and improved performance with Node.js 22. Enhanced the OpenTelemetry batch processing logic to increase trace throughput and reliability, supporting better observability in production environments. Removed unused scripts and updated TypeScript configuration to streamline build and CI processes, resulting in faster builds and easier maintenance. Utilized TypeScript, Node.js, and dependency management skills to ensure reproducible builds and maintainability, with all changes aimed at improving stability and developer experience.
