Worked on the DataDog/dd-trace-js repository to address baggage extraction stability in distributed tracing systems. Focused on backend development and testing using JavaScript, the work involved refactoring the baggage cleanup process to ensure stale baggage items were cleared before extracting new ones. This approach prevented leakage of outdated baggage into new traces and outbound messages, including scenarios where the baggage header was absent. Comprehensive tests were added to validate the fix and cover no-header cases, improving trace integrity and reliability. The changes reduced debugging time for baggage-related issues and strengthened confidence in deploying tracing updates across distributed services.
