Ben Plommer focused on stabilizing and modernizing the build and release pipeline for the typelevel/catapult repository during April 2025. He upgraded the Scala version to 2.13.16 and reconfigured the Scala Build Tool (sbt) setup, targeting improved reliability and faster build performance. By updating build configurations and refining CI/CD workflows, Ben reduced flaky builds and streamlined the release process. His work leveraged skills in build automation, CI/CD, and YAML, resulting in a more maintainable and forward-compatible pipeline. The changes addressed feedback loop delays and enhanced traceability by linking updates directly to specific commits, supporting ongoing project scalability and maintainability.
