Over ten months, Daniel Minikin engineered automation and CI/CD solutions across the input-output-hk/catalyst-voices and catalyst-ci repositories, focusing on maintainability and governance. He implemented reusable GitHub Actions workflows for project field validation, automated label synchronization, and cross-repo CI dependency updates, leveraging Python scripting and shell automation to reduce manual toil and improve data integrity. In catalyst-voices, Daniel enhanced the Flutter-based UI with features like image insertion dialogs and editor upgrades, applying Dart and state management techniques. His work demonstrated depth in configuration management and code refactoring, resulting in more consistent processes, streamlined onboarding, and scalable collaboration across multiple projects.

September 2025: Delivered cross-repo CI dependency update automation for Catalyst CI. Implemented a GitHub Actions workflow that updates CI versions across dependent repositories, supports dry runs, triggers on releases or manual dispatch, and creates pull requests with updated CI versions to improve consistency and streamline dependency management. This work reduces manual maintenance and accelerates CI refresh cycles.
