Back to original languageAbout Gautier
Passionate developer is what best describes me :)
I enjoy discovering new projects and new teams with the goal of creating great things.
To do this, I gladly share the knowledge acquired during my 13 years of experience in Java development and more recently JavaScript.
I am open-minded and enjoy getting involved in open-source projects such as those of the Eclipse Foundation. I also co-organized the Nantes JUG from 2014 to 2021.
