Worked on reliability and maintainability improvements across acidanthera/audk and microsoft/mu_tiano_plus, focusing on embedded systems and firmware development using C and Python. Addressed network boot sequencing by ensuring network modules initialize only after virtio-rng is available, reducing startup flakiness in hardware RNG environments. Enhanced code coverage reporting in acidanthera/audk by implementing LCOV v2 compatibility, strengthening test robustness. Updated the development environment to Fedora 40 for consistency with CI, minimizing environment drift. In microsoft/mu_tiano_plus, consolidated TPM2 PTP API headers to streamline code organization. Emphasized build systems, containerization, and unit testing to improve development throughput and code quality.
