Contributed backend enhancements to the civicrm/civicrm-core repository by implementing a mailing preview feature that enables administrators to access mailings by numeric ID, while maintaining anti-enumeration protections for anonymous users. Leveraged PHP and YAML configuration management to design robust access control, ensuring only users with CiviMail permissions could utilize the new functionality. Improved test reliability by introducing test isolation and cleanup routines using PHPUnit, which reduced duplicate key errors and enhanced CI stability. Maintained project governance by updating contributor records. The work demonstrated a strong focus on security, usability, and maintainability within an open source, test-driven development environment.

Mar 1, 2026March 2026: Implemented targeted enhancements to mailing previews and strengthened test reliability, delivering measurable business value with improved security, admin usability, and CI stability. Key features delivered: - Mailing Preview by Numeric IDs with Access Control: Allows admins with CiviMail permissions to preview mailings by numeric ID when hash_mailing_url is enabled, preserving anti-enumeration protections for anonymous users. Tests verify permission-based access for both admin users and normal API access. - Commits: e52f17d1921b9e0898d56042c8ba20b6f4d5e1d5; e229c47cea86039a627970d5bb30ec54382cc177 Major bugs fixed: - Test suite reliability: Added tearDown with quickCleanup to clean up mailing and group tables between tests, preventing duplicate key errors and improving CI reliability. - Commit: 669a950bc1b514c1dd5f1a84f566b6ebf47a7f3b Contributor recognition: - Added Paul Bütof to contributor-key.yml to acknowledge contribution. - Commit: d4ff66738b978432bb15069e7f17ffd14703c53e Overall impact and accomplishments: - Strengthened security posture for mailing previews while preserving admin usability and anti-enumeration protections. - Improved test isolation and CI stability, reducing flaky tests and maintenance overhead. - Maintained accurate contributor attribution in project governance. Technologies/skills demonstrated: - PHP/CiviCRM backend changes, access control design, and URL hash handling. - PHPUnit-based test development and test lifecycle management (setup/tearDown, quickCleanup). - CI hygiene and test reliability practices.
