Program Manager Data & Analytics at dFakto
I had the pleasure of working with Sébastien for over 7 years on multiple customer projects.
Sebastien brings a rare mix of "artistic" skills, deep UX expertise, and solid business understanding. He consistently designs user experiences that are intuitive, impactful, and aligned with real business goals. His ability to bridge user needs, technical constraints, and client expectations is truly impressive.
Beyond delivery, Sebastien has a strong people and team focus, contributing to a positive, collaborative environment while remaining clearly results-driven. His way of working is agile, structured, and pragmatic, making him a trusted partner for both teams and clients.
Thanks to this unique combination, we were able to deliver many projects successfully and above expectations.

beVault Product Owner at dFakto
I've had the pleasure of working with Sébastien for the past 8 years at dFakto, and I can confidently say he's one of those rare professionals who truly does it all.
As our Lead UX/UI Designer, Sébastien is a real Swiss army knife. His years of experience as a Scrum Master give him a unique perspective that bridges design, development, and team dynamics seamlessly. But where he really shines is in his ability to tackle complex challenges.
His work on beVault is a perfect example. Sébastien took on the challenge of simplifying a data warehouse automation platform, a technically complex software, and made it accessible and intuitive. He didn't just make it look good; he fundamentally improved how users interact with powerful enterprise functionality.
Sébastien was also excellent in our rebranding journey from dataFactory to beVault, bringing strategic vision and flawless execution to what became a defining moment for our product.
Beyond his technical brilliance, Sébastien brings something equally valuable: he lifts the spirit of everyone around him. His positive energy, cultural insight, and genuine care for his colleagues make coming to work better for all of us. He's deeply involved in shaping our company culture and creating the kind of working atmosphere where people genuinely enjoy collaborating, something that's invaluable and too often overlooked.
Any organization would be incredibly fortunate to have Sébastien. He's talented, versatile, and a joy to work with.

I can recommend Sébastien as a person with great education and deep experience of animation, video and web solutions. Sébastien is a reliable, strong, wise and driven colleague always ready to put his energy and stamina to get the job done. He is a responsible co-worker with a great skill to analyze and summarize ideas. For Sébastien the job is always the most important thing to do. 
Peter Van Gorp
Content Manager at Instruxion
I've had the pleasure to work with Sébastien for quite some years. As a multi-talented developer of animations, video and all sorts of (interactive) applications, he always succeeds in finding and proposing the right solution for clients and colleagues. At the same time, Sébastien works very fast and thoroughly, in order to meet short deadlines, without compromising.
