Worked on the tenstorrent/tt-metal repository to enhance CI/CD workflows and C++ testing infrastructure, focusing on automation and DevOps best practices. Developed a robust, rollback-capable CI flow for BH 20-core hardware validation, introducing a new C++ testing workflow that builds artifacts and runs unit tests using Bash and YAML. Transitioned CI runners to a harbor-based setup, refined Docker image references, and implemented validation checks to maintain stability. Streamlined Docker image management by adopting regctl for retagging, improving pipeline efficiency. Stabilized CI benchmarking by reverting workflow changes, ensuring reproducible performance metrics and a maintainable, reliable CI environment for future development.
