Mathieu RIGARD

Embedded Systems Engineer & Product Maker

bridge between your concept and a reliable product.

Based in Thailand, working Full Remote (EMEA). Expertise in solving complex hardware/software interfacing challenges.

01. Case Studies

Test Automation Framework

CRITICAL SECTOR & DEFENSE

Challenge: Secure a complex and unstable C++ software during a critical development phase.

  • Automated Python testing tool interconnected with the product.
  • Simplified interface allowing system engineers to write their own scenarios.
  • Transformation of manual tests lasting several hours into automated cycles of a few minutes.
IMPACT: Average testing time divided by 30. Reproducibility, reliability, and full traceability.

Interactive Ecosystem (Escape Games)

PRODUCT DESIGN / IOT

Challenge: Create a robust system capable of operating 24/7 in a public environment without technical supervision.

  • Design of 15+ interconnected PCB types.
  • Firmware development and multiple HMI interfaces using Qt.
  • Centralized administration interface and intuitive web interface.
  • Strong budget constraints.
Example of PCB for Escape Game
Control board prototypes deployed in rooms
IMPACT: Total reliability (0 failures, 0 bugs). Several commercial rooms in operation for multiple years.

02. Technical Expertise

Software

  • C / C++ (Qt)
  • Python (Automation + HMI)
  • CMake / Git / Docker
  • Embedded Linux

Hardware

  • KiCad
  • Ethernet, SPI, I2C, etc...
  • Touch HMI Design
