Worked on stabilizing the CI and test environments for the sonic-net/sonic-buildimage repository, focusing on reducing flakiness and improving feedback cycles. Addressed intermittent build failures by locking cargo-tarpaulin to a compatible version, preventing ruzstd API-related issues in Rust-based workflows. Enhanced test discovery reliability by introducing a pytest.ini file to enforce default norecursedirs settings across the main repository and its submodules. These configuration management efforts, utilizing Python and Rust, reduced CI noise and improved release reliability. Demonstrated a disciplined approach to dependency management and test standardization, aligning CI practices with broader goals for consistency and maintainability across the codebase.
