Trusted by


I design AI products people can trust.


I help healthtech and fintech teams turn complex data and AI into clear, explainable interfaces that increase adoption, conversion and retention. Every decision is grounded in user research and measured against business goals. 20 years of experience, from Sanofi’s AI-driven strategic intelligence platform to Sony Music, Younited Credit, Leetchi and Chugai Pharma.

Leetchi lets people create online pots to collect money securely and collaboratively: invite participants, track contributions and withdraw funds once the goal is reached. A product I redesigned for retention and simpler money collection.


Key Expertise

How I turn complexity into measurable product impact.



1

AI-Driven Experience Strategy

I design AI tools that act as scientific partners, with explainable recommendations, human-in-the-loop workflows and guided reasoning.

2

Research & Data-Driven Decisions

Qualitative and quantitative research, A/B testing and usability scoring validate every hypothesis before it ships.

3

Conversion & Retention

I optimize journeys and key metrics in fintech and healthtech, from instant credit to investment and money collection.

4

Cross-Functional Leadership

I work with product, engineering, science and executives to move from vision to delivery, through workshops and design sprints.


5

Regulated Environments

Experience in pharma and finance, with GxP, HIPAA and accessibility (AA) requirements built into the design from the start.

6

Enterprise & Consumer Products

Scalable solutions for complex B2B tools and mainstream apps, balancing depth and usability.

7

Design Systems & Governance

Robust, tokenized design systems that keep brand and quality consistent across teams and speed up time-to-market.

8

Business Impact

I tie design decisions to north star metrics, so the ROI of design is visible in engagement and conversion.

Working With Me

Freelance missions for healthtech and fintech teams: AI-driven CX, product design for enterprise and consumer apps, UX research and design systems. I work in English, French, Portuguese and Japanese, and I’ve partnered with product, engineering and science teams in Paris, Tokyo and the US.
