I wrote my first lines of code at the age of 11 on a ZX81. A bit later, I loved to code in ADA and Pascal Since then, I've been a software craftsman for 30 years, a student of Laurent Bossavit, Jonathan Peret, and Olivier Azeau. I have also been a software architect, project manager, and team leader. I have worked for various IT services companies and software publishers, including 10 years at Varian Medical Systems and more recently at ITER org. I'm a C# and JS coder from the beginning, I have recently delved into Kotlin with delight. I believe that good development consists of 70% discussion, 20% testing, and 10% coding.
