Building on my experience as Head of Design leading full product revamps (web + mobile) and company-wide rebrands in B2B SaaS scale-ups, plus 7 years serving 60+ clients across 17 countries as a freelance Product Designer, I bring 14 years of expertise across all areas of UX to companies seeking a results-driven Product Design partner.

I help B2B SaaS companies strengthen their product experience, UX maturity and design velocity through strategic UX, user research and high-quality UI execution.

Recent clients: Waltio (crypto tax SaaS), Nèmes Paris (luxury e-commerce), Dive with Buddy (mobile diving platform)

What I do for clients

→ End-to-end Product Design for web and mobile (UX, UI, visual design)

→ UX Research (interviews, usability testing, UX audits, synthesis)

→ Design Systems & UI quality standards (scalable, brand-aligned, maintainable)

→ Strategic support for CPOs, PMs & founders on product vision & UX decision-making

Available for new missions starting March 2026.

Between two chapters in Product Design, I pursued a personal creative project: documenting ocean life through cinema to raise awareness about marine conservation.

Self-taught in cinematography, editing, color grading and screenwriting, I invested in cinema-grade equipment and started producing short films: solo, self-funded, from scratch.

In 2 years:

→ Produced 3 underwater short films, selected in 32 international film festivals (Oceanic Global, Neum, Sea Film Festival, San Diego Underwater)

→ Won 11 awards including Best Short Film, Best Cinematography & Best First-Time Director

→ Screened "The Cosmos Beneath" at the United Nations Ocean Conference (UNOC3, Nice)

→ Created 90+ short-form videos: 1.7M+ total views across Instagram, YouTube & TikTok

This project continues as a personal side endeavor alongside my Product Design work. It reflects the same mindset I bring to design: autonomy, creative problem-solving, storytelling, and delivering quality from zero to one.

Agorapulse is a B2B SaaS social media management platform used in 180+ countries by 11K+ businesses and 35K+ monthly users.

Joined shortly after the company's €17M funding round to build the Design function from the ground up. Led Product Design, UX Research and Brand Design across web, mobile and all marketing touchpoints.
