Developed and deployed a comprehensive CI/CD pipeline for the lf-lang/lingua-franca repository, focusing on automating builds and tests across Linux, macOS, and Windows environments. Leveraging GitHub Actions, Bash scripting, and YAML configuration, the work included setting up cross-platform dependency installation and integrating testing frameworks with coverage reporting. Addressed a specific issue with Python Conda setup on macOS to stabilize continuous integration workflows. This automation reduced manual testing effort, accelerated release cycles, and improved code quality feedback by streamlining test execution and reporting. The solution enabled more reliable builds and safer, more frequent deployments for the project’s multi-language codebase.
