PROFILE
Dawid Urbanowski
Worked on the allegro/hermes repository, delivering targeted improvements across CI/CD, backend, and frontend systems. Upgraded the CI workflow by migrating actions/upload-artifact to v4, reducing build flakiness and aligning with modern GitHub Actions practices. Developed a configurable durability feature for the Topic UI, enabling fallback to a remote datacenter on publish failures, with changes spanning API design, internationalization, and validation logic using TypeScript and Vue. Addressed backward compatibility by reverting Avro decimal-to-JSON conversion, updating dependencies, and refining test coverage. Demonstrated a methodical approach to reliability, maintainability, and cross-layer integration, leveraging Groovy, Java, and JSON throughout the work.

Feb 1, 2025February 2025: Delivered a configurable durability enhancement for Hermes Topic UI by introducing the 'fallbackToRemoteDatacenterEnabled' setting. This allows publishing to fall back to a remote datacenter on publish failures, increasing message durability with explicit latency and duplication trade-offs. Implemented end-to-end changes across the UI, API, data, and internationalization layers, plus validation logic to support the new field.
