PROFILE
Tom Ball
Worked on the google/j2objc repository to modernize build automation and enhance cross-platform compatibility over a three-month period. Focused on upgrading CI/CD workflows by migrating to Java 17, enabling parallel builds, and streamlining test execution using GitHub Actions and YAML. Improved API flexibility by restoring typed array creation for collections and strengthened build robustness for non-jmod JDKs through shell scripting and build system management. Addressed network error handling by updating deprecated Objective-C error keys to align with current iOS standards. Emphasized test-driven development and unit testing to ensure reliability, maintainability, and compatibility across Android and iOS platforms.
