About Yoann

Developer for over 10 years, I am passionate about my profession. I invest myself heavily in my missions, to the point of blending into the company and bringing the maximum of my experience, advice, and sustainable solutions.

✓ Strengthened by my long-term missions, I know how to perform in complex and high-pressure environments and contexts.
✓ I supervised a team of 4 developers and an integrator in a national-scale project for 4 years.
✓ I am a good teacher, open to suggestions, and enjoy discussing ideas. My view is that nothing is set in stone.
✓ I am curious and invested, I seek to learn and improve. I don't limit myself to my primary scope; I'm a jack-of-all-trades and always seek to simplify my work environment and that of my colleagues.
✓ I dislike doing the same thing twice. I optimize my code for maintenance and scalability. I always look for possibilities to prepare the future of the project.

/!\ If you like being told things directly and want people on your project to be fully committed, don't hesitate to contact me to discuss what you want to achieve and let's make your project a reality. /!\
