Worked on enhancing the schubergphilis/terraform-aws-mcaf-s3 repository by delivering a user-facing feature that improved S3 bucket lifecycle rule configuration. Focused on enabling support for an empty prefix when no filter is provided, the work ensured compatibility with newer AWS provider versions and exposed the configuration through module outputs. The approach emphasized maintainability by cleaning up test-related outputs and applying Terraform formatting standards to support reliable CI processes. Using AWS, Terraform, and HCL, the developer documented incremental changes to handle empty filters correctly across provider versions, reducing upgrade risks and aligning the module’s behavior with evolving AWS provider requirements.
