During January 2025, this developer implemented automated Checkstyle CI workflows across the PSMRI/Common-API, PSMRI/MMU-API, and PSMRI/FLW-API repositories to enforce Java coding standards. Leveraging GitHub Actions and YAML, they standardized code quality gates by adopting a shared Checkstyle configuration with Java 17, ensuring consistent style checks on pull requests to master and develop branches. Repository hygiene was improved by updating .gitignore files to exclude generated logs and outputs, which enhanced pull request quality and reproducibility. Their work focused on CI/CD automation and code quality, reducing style-related defects and streamlining the review process across multiple Java-based APIs.
