Hey, I'm Bastien!

I am a Product Designer with 3 years of experience in the tech industry. Since childhood, I have always been driven by the desire to build things with my own hands. Whether using Lego or exploring the creative world of Minecraft, I constantly sought to bring my imagination to life. These early outlets fueled my creativity and laid the foundation for my journey in digital design.


Outside of work, I am passionate about the gaming world, from gameplay mechanics to esports competitions. I also build creative projects for fun (like this website, built from scratch!) to sharpen my HTML, CSS, and JavaScript skills. This allows me to strengthen my interaction design expertise and bring even more value to product teams.
