Tomek worked on the stackrox/scanner repository, delivering a cross-module upgrade of YAML processing libraries to modern v3-based tooling. He replaced legacy dependencies with go.yaml.in/yaml/v3 and sigs.k8s.io/yaml, consolidating Go modules to improve YAML parsing reliability and Kubernetes manifest compatibility. Focusing on dependency management and Go modules, Tomek’s work reduced parsing-related risks and established a more maintainable codebase. Although no major bugs were fixed during this period, the upgrade laid a stronger foundation for future features and reduced maintenance overhead. His engineering approach emphasized long-term stability and compatibility, addressing evolving requirements in YAML handling for the project.
