Worked on the broadinstitute/cromwell repository to address WDL 1.1 runtime compatibility, focusing on resolving docker and container attribute issues for local and SFS backends. The primary contribution involved a targeted bug fix that improved cross-backend compatibility and reduced runtime errors for WDL 1.1 workflows. Collaborated with a co-author to implement and validate the solution, ensuring maintainability and clear attribution within the codebase. Utilized Scala and YAML to deliver the fix, leveraging Docker and GitHub Actions for testing and deployment. The work enhanced workflow reliability and reduced support friction, contributing to smoother backend operations for WDL 1.1 users.
