Hello👋
I am a **Product Designer with over 10 years of international experience (China, Japan**, and **Australia)**. I specialize in creating innovative digital products and services that **meet user needs while achieving your business goals**.
My strengths lie in myadaptabilityandcreativity**. I enjoy tinkering with and testing new tools, always seeking practical solutions. **I use AI-powered technologies like Lovable and Cursorto develop functional solutions.
✅ Here are some problems I solve:
Design debt
Applications age and their UX degrades. I analyze the situation and propose tailor-made improvement strategies.
Impact: fewer bugs, simplified maintenance, and happier users (thus more productive ☺️)
Heterogeneous ecosystem
Do your tools lack consistency? I implement Design Systems to unify the experience.
Impact: a coherent whole and reduced development time.
Misaligned teams
Is communication between designers, developers, and POs difficult? I organize workshops to align teams effectively.
Impact: better synergy and productivity. 🤝
Testing new hypotheses
Need to validate your ideas quickly? I use AI tools to create prototypes in record time.
Impact: validation in days instead of weeks.
Vague user feedback
Do surveys not yield actionable data? I apply methods like HEART and CASTLE to obtain useful insights.
Impact: a product strategy based on concrete data.
✅ Why me?
For me, design is a state of mind, not a rigid method. It's a blend of creativity, curiosity, and know-how that allows solutions to be adapted to each context. I focus on code and AI as design tools.

Biogen was therefore looking for a solution to promote the effectiveness of its treatment and allow patients to make their voices heard by their neurologist: create a mobile application to track the progression of the disease.MissionThe timing was very important for Biogen, and we managed to design, develop, and launch the pilot in the Japanese market in less than 3 months.1. I conducted quick research to understand the disease and its symptoms: internet research, scientific reports, discussion with a Japanese neurologist specializing in the subject.2. Concept creation: patients answer a series of questions once a month and rate their answers on a scale from -5 to +5. Example: I can use my smartphone without difficulty.3. Interactive prototyping of the application on Figma to validate the concept.4. Close collaboration with frontend and backend developers. The application was functional in 3 sprints of 2 weeks.ToolsFigma, Miro, ChatGPT, Claude
