PROFILE
Thiébaud Weksteen
Over five months, contributed to google/conscrypt by modernizing its testing and build infrastructure, enhancing code quality, and improving security features. Migrated legacy JUnit 3 tests to JUnit 4, updated Gradle build configurations, and streamlined CI/CD workflows using GitHub Actions and YAML, which improved maintainability and reduced review overhead. Introduced automated code formatting checks for C++, Java, and C files, supporting consistent code hygiene. Refactored Certificate Transparency logic for modularity and clearer metrics reporting, using Java and native code integration. Stabilized TLS Encrypted Client Hello handling by refining error reporting and test correctness, reducing production risk and strengthening SSL/TLS reliability.

Jan 1, 2025January 2025: Focused on improving modularity and metrics for Certificate Transparency (CT) in google/conscrypt. Implemented a CT module refactor that decouples TrustManagerImpl from CT logic by introducing a dedicated CertificateTransparency class, preserving existing CT functionality while enabling better maintainability and testability. Refactored CT verification metrics reporting and related metrics classes to improve visibility and future extensibility. This work lays the foundation for enhanced CT support and easier future feature integration without changing user-facing CT behavior.
