Confirmed Software Engineer / Engine Programmer at Ubisoft

But also as a hobbyist, Digital artist, Content creator on YouTube and Poet

>_ Hello, World!

There is surely a lot to say about me but I will try to sum it in a few words. First of all, you need to know that I’m passionate about computer science, low level programming, video games and obviously game engines, otherwise I wouldn’t be an engine programmer.

You don’t need to win every time. Even if one day, you are overcome or defeated… As long as you transmit your heart and your will to others, everything will be fine.

Personal side

I’m fluent in French, English and I can understand and speak German, but with more limited applications. I like writing, especially poems and philosophical thinking. I’m also a video content creator on YouTube, I hold a pedagogic YouTube channel with more than 10 000 subscribers about C++, programming and game engine programming. I’m also an amateur digital artist, you will find all my creations on this website or on my DevianArt. You may like it or not but I really like putting love and meaning in all my creations. Here’s an extract of the last 3 digital paintings :
