PROFILE

Tszwingli

Worked on the Shepherd-BMS repository for Northeastern-Electric-Racing, focusing on embedded systems and firmware development in C. Over three months, contributed to the reliability and maintainability of the fault management subsystem by introducing critical fault prioritization, simplifying the fault handling API, and synchronizing submodule dependencies. Enhanced the state machine logic to distinguish and handle critical versus non-critical faults, reducing alert noise and improving triage. Addressed a key bug to ensure accurate fault detection and clearing by correcting pointer usage in fault evaluation. Maintained clear traceability through documented commits, supporting easier code review, regression tracking, and future certification efforts.
