Worked on the stanford-ssi/samwise-avionics repository to enhance the avionics PCB design by restructuring KiCad component UUIDs and updating capacitor and resistor models for improved design integrity and traceability. Introduced a new model directory structure and comprehensive production definitions, including zones, ground and power planes, and signal routing areas, to support manufacturability and electrical performance. Addressed a critical USB-C footprint reference issue to prevent misrouting and production errors. Leveraged skills in electronics engineering, hardware development, and PCB design using KiCad, focusing on reducing rework risk and streamlining the transition from design to manufacturing and bill of materials.
