During December 2025, this developer refactored the VCF constants and CAN interface within the hytech-racing/VCF repository, focusing on improving maintainability and reliability for embedded systems. Using C++ and leveraging expertise in hardware interfacing and real-time systems, they decoupled constants from the main module, standardized naming conventions, and stabilized the CAN setup to reduce integration risks. Their work resolved a critical CAN declaration error and clarified module boundaries, resulting in more robust VCF communication. They also enhanced documentation and collaborated closely with the team through co-authored commits and code reviews, supporting smoother onboarding and future feature development.
