During March 2026, contributed two features focused on modernizing CI/CD workflows for the okx/optimism and ethereum-optimism/optimism repositories. Migrated the op-deployer Docker build from CircleCI to GitHub Actions, enabling atomic builds, in-container contract compilation, and improved cross-platform compatibility. Introduced per-image change detection for Docker builds, centralizing image references in a JSON configuration and using environment variables to enhance security and maintainability. These updates reduced unnecessary builds, improved fork pull request handling, and hardened deployment processes. Work was implemented using Bash, YAML, and Go, emphasizing reproducible builds and faster, safer release cycles without introducing new bugs.
