At Soil Capital, I work as a part-time Lead Product Designer with a strong strategic focus, deeply involved in complex subjects combining technology, agriculture, and environmental transition.

I act as a true product partner, transforming business needs and complex data into clear, actionable, and high-value experiences. My goal: to align product vision, user needs, and business impact.

I manage end-to-end design projects—from scoping to production—by structuring user journeys, defining robust interfaces, and establishing effective iteration cycles with the teams. I also play a key role in structuring the design system, setting sustainable standards to support the growth of the product and teams.

Beyond production, I actively contribute to structuring and maturing the organization's design capabilities. I mentor a junior designer, focusing on developing their skills, and I support the marketing team's graphic designers to elevate the overall quality level.

As the guardian of the visual identity, I ensure brand consistency across all touchpoints. I work closely with the marketing teams to define and produce high-impact materials (events, social media, campaigns...), ensuring strong alignment between product, brand, and storytelling.

My role thus lies at the intersection of design, strategy, and organization: structuring, aligning, and improving quality—with a constant focus on the real impact of design.

As a freelancer, I support companies and startups in their product design and brand identity challenges, with a user-centered and impact-oriented approach.

I recently worked (for 1 year) as a Product Designer at My Impact Tool, a platform dedicated to measuring and managing the environmental and societal impact of organizations. In this role, I collaborated closely with product teams to design useful, understandable, and engaging experiences. I facilitated UX workshops (scoping, user journeys...), conducted user testing to validate hypotheses, and contributed to the continuous improvement of the product.

I also participated in the design of an AI agent, working on both the user experience and the creation of its visual identity, to offer a fluid, coherent, and embodied interaction.

In parallel, I assist various clients in creating complete visual identities: from defining the brand platform to developing detailed graphic charters. My goal is to design visual universes that are distinctive, coherent, and tailored to the challenges of each project.

These missions allow me to navigate between product, branding, and innovation, while maintaining a strong focus on the clarity, utility, and impact of the design.

At Axance, a pioneering digital ergonomics agency in France (now Creative Tech within Devoteam), I strengthened my user-centered design expertise in complex and demanding environments.

As a Visual Interaction Designer, I worked using agile methodologies, closely collaborating with product teams and business stakeholders. I facilitated UX workshops (personas, user journeys, roadmap...), fostering the emergence of shared visions and decision-making. My role also included synthesizing and clearly presenting recommendations to clients.

I supported the design of digital products from start to finish: from quick sketching to explore ideas, to structured wireframing, and interactive prototyping for testing and validating experiences. Storyboarding allowed me to bring use cases to life and visualize solutions in real-world contexts.

I also contributed to formalizing guidelines, UX specifications, and user flows, ensuring the consistency, quality, and feasibility of the designed interfaces.

This experience allowed me to consolidate a rigorous approach to UX, combining strategic vision, facilitation, and precision in execution.
