Worked on the dbos-transact-ts repository to enhance observability and reliability in backend retry workflows. Focused on a critical bug fix involving OpenTelemetry span propagation, ensuring that child spans generated during retries are correctly nested under their respective step spans rather than the broader workflow span. This was achieved by reusing the existing step span and wrapping each retry with runWithTrace in conjunction with runInStepContext, all implemented in TypeScript. Local validation confirmed improved trace accuracy, reducing noise and supporting more consistent downstream instrumentation. The work strengthened operational visibility and debuggability, enabling faster issue resolution and better business insight.
