Dan contributed to the srl-labs/containerlab repository by developing cross-tool inventory automation that streamlines network deployment workflows. He implemented support for generating Nornir inventory files, introducing a new simple inventory format and integrating platform-specific naming conventions for Nornir, Scrapli, and Napalm. Using Go and YAML, Dan enhanced node registration to include platform attributes, improving interoperability across automation tools. His work aligned inventory generation with existing Ansible workflows, reducing manual configuration and accelerating deployments. The feature addressed the need for unified inventory management in network automation, demonstrating depth in Go programming, templating, and inventory management within a complex, multi-tool environment.
