PROFILE

Mike Chang

Over eight months, Changml engineered robust build automation and CI/CD systems for the o3de/o3de repository, focusing on cross-platform reliability and reproducibility. He introduced toolchain version pinning and automated environment setup using CMake, Gradle, and GitHub Actions, which standardized builds across Windows, Linux, and Android. By integrating compiler caching, optimizing artifact management, and refining test suites, Changml reduced build times and improved feedback cycles. His work included scripting in Bash and PowerShell to modernize installation and signing workflows, while addressing flaky tests and licensing issues. The solutions demonstrated deep understanding of build systems, configuration management, and large-scale DevOps practices.
