Jack Z.

I help turn product ideas into practical prototypes by connecting mechanical design, embedded control, and software.

My focus is on parts and assemblies that fit their electronics, mechanisms that can be controlled and tested, and clear documentation that lets the next engineer continue the work.

SERVICES
• SolidWorks 3D parts, parametric assemblies, and mechanical design
• AutoCAD technical drawings and 2D-to-3D development
• 3D-printable parts, mounting arrangements, and iterative prototype refinement
• Sensor, actuator, and ESP32 integration for interactive hardware
• Device control dashboards and Python tools for testing and demonstration
• Engineering simulation, design checks, and technical documentation

SELECTED PROJECTS
Active car spoiler: mechanical assembly and aerodynamic analysis connected to ESP32 firmware, servo calibration, safety controls, and a React dashboard.

Vandi fuel-cell robot car: mechanical design and packaging, AI training, simulation, control algorithms, and the control front end. This was a three-person interdisciplinary project; teammates owned the fuel chemistry and PCB/BMS design.

Robot basketball: led an eight-person team that won first place in the interdepartmental competition; my design contribution was the shooter and its placement in SolidWorks.

Nylon replacement handle: designed and iterated a 3D-printed repair around an existing blade and an elderly user's grip needs.

I am a Hong Kong-based Robotics Systems Engineer and PolyU Mechanical Engineering graduate, with four years of independent engineering and software project work. I work in English, Cantonese, and Putonghua.

Share your sketches, existing CAD, photographs, component dimensions, and intended function. I can help define the next buildable step and the files, prototype work, and checks needed for that milestone.
