Jon Barber
Worked on the input-output-hk/acropolis repository to enhance CI/CD automation, focusing on reliability, efficiency, and maintainability. Over five months, delivered features such as main-branch aligned GitHub Actions pipelines, overnight bootstrap test automation, and omnibus CI workflow enhancements. Addressed issues by optimizing resource usage, improving test coverage visibility, and stabilizing build processes. Leveraged Bash, TypeScript, and YAML to implement robust scripting and workflow automation, while refining system administration practices. The work reduced feedback cycles, minimized build failures, and established scalable automation foundations, enabling safer releases and smoother integration of future features within a continuously evolving development environment.
