During a two-month period, John Lakis enhanced the tenstorrent/tt-metal repository by building robust CI/CD workflows and improving C++ testing infrastructure. He introduced a rollback-capable CI flow for BH 20-core tests, implemented a new C++ testing workflow to automate artifact builds and unit tests, and transitioned the runner setup to use harbor-based Docker images. Leveraging skills in CI/CD, Docker, and YAML, John streamlined image management by adopting regctl for Docker image retagging, which improved pipeline efficiency. He also stabilized CI benchmarking by refining runner selection and workflow logic, resulting in more reliable, reproducible builds and a maintainable development pipeline.
