Contributed to the UCSD-E4E/smartfin-fw3 firmware by developing structured JSON reporting for manufacturing test results, enhancing traceability and automation in embedded systems. Improved cross-platform compatibility through conditional compilation and platform-aware JSON handling, ensuring reliable test output across Particle and non-Particle builds. Enhanced documentation for I2C drivers, task interfaces, and manufacturing tests, clarifying API usage and onboarding processes. Addressed robustness in sensor data handling by updating temperature read functions to return NaN on invalid registers, preventing data misinterpretation. Utilized C++ and Markdown to implement features, fix bugs, and maintain clear, maintainable code, supporting both hardware testing and software validation workflows.
