Senior🎓
Top SchoolChang Choi is a Staff Embedded Software Engineer with a decade of experience building medical and bio-signal devices, currently driving firmware development at ZOLL Medical Corporation. He blends a strong academic foundation from Johns Hopkins (MS ECE, 3.8 GPA) and hands-on expertise from roles in clinical research and neurotechnology to deliver real-time, safety-critical embedded systems. His background spans ARM Cortex-M platforms, custom signal-processing algorithms for ECG/HRV, and cloud-connected ML systems for patient monitoring, reflecting both low-level firmware and higher-level system integration skills. Chang has repeatedly improved test automation and algorithmic pipelines—cutting manual processing time by ~80% in prior research—which signals a practical focus on reliability and efficiency. Comfortable teaching and translating algorithms across Matlab, Python, and embedded C, he bridges research and product development in regulated medical environments. Notably, his early work on ML-based fatigue monitoring and pediatric ICU monitoring platforms highlights a knack for bringing research prototypes into clinically useful systems.
