Freelancer profile translated to English.
Back to original languageAbout Mathis
I am a software engineer specializing in embedded systems and technical tool development, with a strong interest in simulation, data processing, and complex systems.
I have worked on projects related to space and embedded systems, particularly on the development of simulators, physical system modeling, and signal analysis. These experiences have led me to work on both low-level development (C/C++, Linux) and Python tools for data processing and visualization.
I am particularly interested in projects that bridge the gap between software and real-world systems: simulation, sensors, signal processing, or technical data processing.
I can contribute to:
- Python / C++ development
- Simulation and modeling
- Data processing and analysis
- Internal tools and automation
- Linux and embedded environments
I prefer technical projects where I can bring real value, while remaining flexible for more targeted assignments.
