From product to business impact.
Without friction.
I combine design, data and code to reduce friction, improve adoption and drive growth.
✓ Product design • SaaS development • Integrated strategy
Hello, I'm Sophie
My role
Remove the friction between strategy, design and development to turn an idea into a clear, high-performing, useful product.
What makes the difference
I don't "just" design interfaces.
I use data to guide product decisions upstream, to build only what creates value:
→ more engagement
→ more business impact

Antoine Carossio
YC 2023Sophie anticipates difficulties, which greatly eased our collaboration. She doesn't just create aesthetic designs; she carefully evaluates their impact and feasibility, a valuable asset for any technical team. I recommend Sophie to any company looking for someone able to effectively bridge product, design and development.

Simon Bucquet

With Prodju, we now have a product that meets our users' needs and a clear product roadmap. Every step was validated, which saves time and reduces the risk of costly mistakes.

Frédéric Breussin

I had the pleasure of working with Sophie on our software's user interface. Thanks to her dual expertise in product design and JavaScript development, she designs interfaces that are effective and directly shippable, cutting time-to-production. She delivers UX tailored to user needs, with real product vision, fast.
