PROFILE

Tanja Bunk

Over a three-month period, Thomas Bergman enhanced the RasaHQ/rasa-calm-demo and RasaHQ/rasa-sdk repositories by focusing on test reliability, dependency management, and observability. He refactored and stabilized end-to-end testing suites, upgraded Rasa and Python dependencies, and improved build automation using Python and Makefile. In the rasa-sdk, he modernized tracing integration by switching Jaeger tracing to OTLP, reducing protobuf issues and aligning with OpenTelemetry standards. His work included updating CI workflows, dropping legacy Python versions, and refining documentation. These efforts improved deployment confidence, build reproducibility, and tracing reliability, demonstrating depth in backend development, DevOps, and continuous integration practices.

Work History

September 2025

In September 2025, the rasa-sdk focused on strengthening observability and modernizing runtime tooling to deliver more reliable deployments and faster release cycles. Key work included tracing backend integration enhancements and CI/runtime updates that together improve reliability, maintainability, and business value. Specifically, tracing improvements switch JaegerTracerConfigurer to use OTLP internally, enhancing compatibility and reducing protobuf-related issues, while CI/tooling updates dropped Python 3.9 in favor of 3.12/3.13 and updated the release version to 3.14.0.dev6. These changes were supported by adjusted dependencies and test scaffolding to preserve integration test integrity across backends. The overall impact is more robust tracing across deployments, smoother development experience, and a clearer path to production-readiness for customers.
