Joern Wege developed security tooling and infrastructure across google/tsunami-security-scanner-plugins, google/security-testbeds, and google/osv-scalibr, focusing on vulnerability detection, reproducible testbeds, and software inventory extraction. He implemented Docker-based test environments for Apache Pinot and Kafka UI, enabling isolated, repeatable security validation workflows. In Go and Java, Joern built and maintained plugins for CVE detection, improved code organization, and enhanced test reliability through configuration management and cleanup routines. His work included robust file parsing for version extraction, CI/CD pipeline stabilization, and documentation updates, resulting in maintainable, scalable systems that streamline vulnerability analysis, remediation validation, and open source component inventory.

In September 2025, delivered significant improvements across two repositories, focusing on expanding OSS inventory capabilities and simplifying deployment workflows. Major work includes Node.js version extraction via NVM and .node-version support in osv-scalibr, and replacing the Pinot deployment with Docker Compose in security-testbeds. These changes improve accuracy of component/version inventory, reduce maintenance burden, and enable reproducible deployments.

March 2025 monthly summary for google/tsunami-security-scanner-plugins focusing on business value and technical achievements. The primary deliverable was stabilizing Airflow credential testing by disabling batched execution, which reduced test flakiness and improved reliability of credential detection. This targeted bug fix is associated with commit 663c13df3390eea34d4bbd40a14a6b705b1d9108, where batched() now returns false to stop batch processing. The change enhances CI determinism, reduces pipeline noise, and strengthens security workflow reliability.
