Worked on the SCFormulaElectric/USC-Electrical-Systems repository, delivering a comprehensive relayboard design overhaul focused on enhancing hardware reliability and maintainability. Applied electrical engineering expertise and KiCad for schematic updates, introducing new components and modifying footprints to support future scalability. Improved development workflows by updating tooling and implementing repo hygiene measures such as refining the .gitignore file, which streamlined setup and reduced integration risks. Addressed relayboard behavior through targeted fixes, ensuring more robust hardware-software interfaces. The work enabled faster iteration cycles and clearer release readiness, leveraging skills in PCB design and electrical engineering to support ongoing hardware integration efforts.
