"Lucas is one of the most complete UX professionals I’ve worked with.
He led the entire UX/UI of PANDA from initial framing to multiple releases, turning it into a reference product at Renault Digital.
His work introduced UX research, testing and design standards still used across the organization today.
A rare blend of strategic thinking, deep craft excellence and flawless execution."
Esra Soner
Head of Digital Performance @Renault Digital
"Lucas doesn’t just create beautiful design; he builds visual systems that are durable and high-performing.
The full rebranding he led at Agorapulse was a true turning point: nearly 5 years later, the foundations he created are still in use and continue to carry the brand.
His work was essential in strengthening our credibility in Europe and supporting our strong growth in the United States.
For a marketing director, having a partner who combines creative vision with a deep understanding of international business challenges is invaluable.”
Yoann Fondelot
Director of Marketing & Business Development Europe @Agorapulse
“Lucas is one of the rare UX designers who excels equally in strategic vision, hands-on research and high-craft UI.
He combines long-term product thinking with real user insight and delivers designs that developers can integrate flawlessly.
A great partner to work with ; sharp, reliable and genuinely enjoyable to collaborate with.”
