Back to original languageAbout Quentin
Product Designer and Cognitive Psychologist
I blend psychology and Product Design to create digital products (web, mobile, SaaS) designed to convert, retain, and last. My approach is based on the real mechanisms of attention, memory, decision-making, and motivation. The result: less friction, more engagement, and user journeys adapted to your users' cognitive load.
Solid and Varied Experience
Over 15 projects led, from the zero phase to products used by millions of people. I have worked in sectors as diverse as IoT, fintech, education, real estate, and law. This diversity allows me to quickly get to the right question, whatever your context.
End-to-End Support
I am involved in the entire product design cycle: framing and ideation workshops, UX research (interviews, data analysis, benchmarks), user testing (moderated, unmoderated, A/B), interface design and prototyping, UX and UI audits. Depending on your needs, I can manage a complete project or intervene on a specific phase: framing an MVP, redesigning an existing product, structuring a product strategy.
Work Method
Rigorous upfront framing, structured deliverables, direct communication. Every design decision is justified and documented, to help you evolve your product and maximize your results.

Collaborating with Quentin was an excellent experience that I highly recommend! His ability to design user journeys that are simple, ergonomic, and friction-free truly enriched my project. Quentin brings real intelligent and strategic thinking to product development, proving to be a valuable advisor despite my extensive experience in IT projects. I now have a perfect vision of what I want for my product and the direction I want to take the final design. A big thank you for his quality support. I look forward to working together again on future projects, once the necessary funds are raised to finance my MVP. We will then be able to fully deploy your talent without budget constraints 🚀 Thank you Quentin, see you very soon!
