PROFILE
Mei-hsiang Chang
Worked on the OpenLiberty/open-liberty repository to enhance security and reliability in Java-based backend systems, focusing on FIPS 140-3 compliance and data integrity. Developed FIPS-aware configuration and test gating for JPA and MicroProfile JWT modules, ensuring cryptographic settings aligned with regulatory requirements. Improved build automation by introducing rules to skip non-essential tests in FIPS mode, streamlining continuous integration and reducing maintenance overhead. Delivered SHA-512 based checksum algorithms for API and UI data integrity, and expanded UI testing infrastructure. Utilized Java, JUnit, and cryptography best practices to address security, configuration management, and testing challenges across multiple modules and environments.

Jun 1, 2025June 2025: Implemented FIPS 140-3 profile configurations across JPA test modules and MicroProfile JWT 2.x TCKs, aligning cryptographic module settings with FIPS requirements. Added FIPS-aware test gating to skip tests when FIPS mode is enabled, preserving test integrity in FAT modules. These changes strengthen security posture, reduce flaky failures, and support faster release readiness.
