Worked on the concordia-fsae/firmware repository, delivering enhancements and fixes for embedded vehicle control and battery management systems. Focused on C programming and firmware development, the work included expanding GPIO pin multiplexing and improving hardware configurability to support evolving vehicle architectures. Addressed safety and reliability by aligning GPIO naming with datasheet specifications and implementing a precharge timer in the BMS, reducing misconfiguration risk and enforcing safe precharge durations. Refined contact cycling logic in the BMS to ensure stable power management, demonstrating attention to safety-critical state management and threshold-based control. Emphasized maintainability and traceability across hardware and software integration.
