Worked on the tenstorrent/tt-xla repository to enhance test infrastructure ownership and streamline review processes. Updated the CODEOWNERS file using YAML to include a new team member responsible for tests and continuous integration, aligning code ownership with ongoing TT-XLA test infrastructure initiatives. This change improved accountability and maintenance by ensuring that test and CI code receives proper reviews, which in turn reduced onboarding time for new contributors and increased CI reliability. Focused on code ownership management and DevOps practices, the work fostered clearer collaboration and more reliable test results, supporting the long-term maintainability of the TT-XLA project’s testing workflows.
