• Designed 5+ analog/digital PCBs (power supply, protection circuits) in EasyEDA; validated designs via LTspice simulation and lab testing, achieving zero critical failures on final revisions. • Debugged PCB prototypes with multimeters; resolved hardware faults across multiple board revisions to meet design specifications.

• Performed root cause analysis on 100+ medical devices via schematic and signal interpretation, diagnosing and repairing analog front-end failures. • Diagnosed and repaired ECG, SpO2, and NIBP analog front-end faults across the full biosignal acquisition chain on 50+ multi-parameter patient monitors; verified signal accuracy post-repair against clinical specifications, achieving 85% return-to-ser

Gained hands-on exposure to MRI, CT, and X-ray clinical workflows at GE Healthcare; supported preventive maintenance and device calibration procedures on imaging equipment.

Developed embedded C firmware for a temperature control system on AVR microcontrollers, implementing timer-based PWM control and SPI/I2C peripheral communication for sensor interfacing.
