Role: Lead embedded engineer — hardware design, firmware, and system integration.
Tech: TM4C129 microcontroller, custom PCB, Embedded C, USB 2.0, precision analog front-end.
Summary: I designed and implemented an automated system for measuring solar cell efficiency that reduced measurement time from ~45 minutes to under 4 seconds while improving accuracy through careful hardware and firmware design. The project included PCB design for precise voltage/current sensing, real-time data acquisition, thermal drift mitigation strategies, and high-speed USB export for laboratory workflows.
