Worked on the facebook/fboss repository to deliver hardware readiness verification for both pre-landing and live hardware modes. Focused on onboarding and validating 145 readiness checks, this effort expanded system verification coverage and reduced deployment risk in production environments. The work involved consolidating changes into a single, traceable changeset, enabling faster validation and improved traceability across the codebase. Leveraged C++ for development, with an emphasis on build system management and system programming. The approach centered on hardware-software integration and cross-functional collaboration, ensuring stability and risk reduction without major bug reports during the period, and strengthening production risk management processes.
