Guillaume Dusseux-Gicquel
I’m a product designer from Brittany, focused on visual systems, interface craft and product experiences built for real-world use.
I grew up with science fiction, fantasy worlds and early digital interfaces. To me, games and software were never just tools or screens to use. Like films, books or music, interfaces can create a mood, suggest a world and make people feel something.
They had their own logic, atmosphere, rules and identity.
That still shapes how I look at product design today. I care about how a product works, but also about what it communicates through its rhythm, words, details and visual language.
My path into design was not linear. Before product design, I worked across research, front end development and product delivery.
Real business products
I work on B2B platforms, SaaS products, e-commerce products, mobile apps and professional workflows.
Most of my work sits between Product, Engineering, business teams and end users. I deal with roles, permissions, pricing logic, sales processes, operational feedback and legacy products that still need to ship.
I have built design systems, worked in startups and large companies, and often acted as the only designer or lead designer on the product side.
Beyond usability
I do not see product design as only making screens clean and efficient.
Some of the products, games and software that shaped me were made with small teams, limited budgets and clear technical limits. Yet they often had more personality than many polished digital products today.
You could feel that someone had made decisions. Someone owned the world, the interface, the rhythm, the small details. It was not just usable. It had intent.
That is what I still look for in my work: making products clear, accessible and reliable, while giving them enough identity to feel specific, owned and alive.
