PROFILE

Johannes Brüderl

Worked on the redpanda-data/connect and redpanda-data/common-go repositories, focusing on reliability and maintainability in data ingestion and audit logging. Delivered a fetch_max_wait configuration option for the Redpanda input, improving batch filling and throughput stability when ingesting data via franz-go. This feature enhanced the predictability of downstream analytics pipelines and demonstrated skills in Go development and configuration management. Additionally, addressed a critical bug in audit logging by reverting a refactor in redpanda-data/common-go, restoring original file paths and Protocol Buffers definitions to maintain compatibility and regulatory compliance. Work reflected careful rollback practices and proficiency with Go and protobuf.

September 2025: Stability and audit-logging reliability in redpanda-data/common-go were restored by reverting the refactor that moved auditlog into a common package. This included restoring original file paths and package structure, undoing the audit log proto definitions and generated Go code refactor to fix broken audit logging. The change was implemented in commit 119fe14ac7c0142b802e3bf374b527d0c9f1ebbd, returning to a proven and maintainable layout.
