About this gig

Have an idea for an electronic or mechatronic product but need help turning it into a working prototype?

I can support your project from the initial concept to a functional and testable prototype, combining mechanical design, electronics, embedded programming and fabrication.

I can help with:

  • Mechanical design and 3D CAD (SolidWorks)
  • Custom electronics and PCB design
  • Arduino, ESP32, ATtiny and other microcontrollers
  • Sensors, motors and actuator integration
  • Embedded C/C++ programming
  • 3D printing and laser-cut parts
  • Assembly, testing and troubleshooting

My previous projects include an automated paludarium with custom electronics and software, autonomous robots for the French Robotics Cup, assistive devices and complete sensor-based prototypes.

Every project is different, so please contact me before ordering to discuss your requirements and define the best approach.
