John Peng is a multidisciplinary engineering leader with 11 years of experience building robotics, embedded systems, and AI-driven tools from prototype to product. Currently Director of Technical Resources in Los Angeles, he blends hands-on hardware work—designing 7-DOF robot arms and self-driving skateboard subsystems—with machine-learning and retrieval-augmented LLM pipelines. He’s contributed front-end improvements to a popular TypeScript/D3 dataviz library, adding interactive chart behaviors and thresholding features, and enjoys AI code generation in his toolchain. John’s background spans embedded firmware for ESP32 wearables, IoT libraries and PCB assembly, plus academic research on legged-robot gait coordination, giving him rare fluency across control, perception, and UX. Colleagues rely on him to translate ambitious research and product ideas into tested systems that perform in the real world.
