About Sebastien

I am a Senior Lead Product Designer and Digital Art Director with diverse and in-depth industry experience since 2008. During my 4 years at renowned agencies like Ogilvy and TBWA as an Art Director for international brands (LVMH, Nestlé...), followed by 5 years as Head of Studio at KRDS, I managed a studio of 10 people in India, while overseeing the agency's brands in key markets such as Shanghai, Singapore, India, and France.

Over the last 7 years, I have specialized in UX/UI, working within the product design teams at Openclassrooms, a leader in EdTech.

My areas of expertise:
- User experience design and improvement
- Interface design
- Creation of strategies based on relevant insights
- Digital activation design
- Creation and art direction of branded visual content
- Film production.

My versatility, passion, dynamism, and agility are assets I bring to every project. You can discover my work and creative universe on Pinterest, and view my CV on my website: cargocollective.com/sbrett/ (currently focused on UI/AD).

Feel free to contact me to discuss how I can contribute to your project or company.
