BUILDING PRODUCTS THAT CONVERT.

Senior Product Designer specializing in Product Strategy and Growth UX, with over 10 years of experience in SaaS products in startups and scale-ups, I support teams on growth, monetization, and product structuring challenges.

I work closely with founders, CEOs, CPOs, and product teams to clarify their offerings, prioritize product decisions, and improve user journey performance. My role goes beyond interface design: I act as a product partner, at the intersection of user needs, product constraints, and business objectives.

Thanks to dual expertise in Product Design and Product Management, I work across the entire product cycle with an impact, arbitration, and results-oriented approach. I specifically support growth UX issues through the optimization of paywalls, onboarding, offer clarification, UX writing, and the definition of clear, conversion-oriented sales arguments.

Areas of intervention:

• Product discovery & UX research: understanding usage, framing product problems and opportunities

• Key journeys & conversion: onboarding, activation, monetization, paywalls

• Design & prototyping: Figma wireframes and prototypes focused on testing and decision-making

• Design systems: interface consistency, scalability, and maintainability

• Product collaboration: close work with tech and product teams

• Multilingual localization

I have worked on products with significant business stakes for Reverso, Fiscalonline, Sight, Twyce, Ott Design, Clarisse Ernoux, Hectar, Brigad, Save, and others in contexts of structuring, optimization, or scaling.

The approach I use is pragmatic, product- and results-oriented: every design decision must serve clarity, activation, and growth.

Looking forward to discussing your challenges! :)
