Engineering Manager
@ Decathlon

Currently, I am the Engineering Manager and Tech Lead of the Decathlon Design System.

I love learning new things every day, meeting enthusiasts, and sharing my knowledge with as many people as possible.
Currently, I also freelance part-time to assist companies with topics related to web development & Design System.. Additionally, I provide free content on these subjects on my blog, my newsletter and my YouTube channel.

I am also passionate about Open Source and am always interested in working on new projects with new people.
