Xinyi Zhang worked on code quality improvements for the Chimera V2 firmware in the UBCFormulaElectric/Consolidated-Firmware repository. Focusing on Python and firmware development, Xinyi refactored import statements to reduce code coupling and enhance readability, which also improved compile times. The work included standardizing protobuf usage throughout the firmware, ensuring consistent serialization and simplifying future maintenance. By documenting testing steps and providing a clear changelist, Xinyi facilitated smoother code reviews and easier onboarding for new contributors. These changes established a foundation for future protobuf-driven enhancements, supporting faster feature iteration and long-term maintainability within the firmware codebase.
