About Martin

Since 2018, I have been helping teams build lasting Design Systems: coherent, scalable, and truly adopted by designers and developers.

My interventions cover the entire spectrum: structuring or redesigning a Figma library, implementing design tokens, automating variants and modes, documentation, governance, and upskilling teams.

Recently at Société Générale (via Devoteam): merged 2 libraries into 1, deployed 500+ variables, redesigned 185+ responsive components, supported 40+ designers.
Before that, at FDJ (via Devoteam): complete redesign of the mobile Design System with light/dark mode switch and tokenization.

I support teams to ensure the DS is actually used through workshops, tutorials, and direct collaboration with developers.

Experience

  • Société Générale
    Design System Manager
    BANKING AND INSURANCE
    March 2024 - September 2025 (1 year and 6 months)
    92800 Puteaux, France
    Within the Design System team, my role was to improve and maintain the Figma libraries used by about thirty designers. The objective was to ensure component consistency, correct past errors, and optimize workflows to make work more efficient.

    My main responsibilities:
    • Structure and optimize Figma libraries to ensure smooth and standardized use.

    • Implement a token system to automate graphic variations, limit errors, and facilitate maintenance.

    • Precisely document each component to ensure better understanding and use of the design system by designers and developers.

    • Support designers in adopting best practices and help them upskill on the tools.

    • Modernize work processes by creating guides, tutorials, and presentations to improve the accessibility and efficiency of the design system.

    • Collaborate with technical and product teams to ensure smooth integration of the design system into projects.

  • ECV Aix-en-Provence
    Atomic and Design System Lecturer
    EDUCATION AND E-LEARNING
    February 2025 - February 2025
    Aix-en-Provence, France
    As a lecturer for Master 1 students, I led a workshop dedicated to the design and documentation of a Design System. I introduced the fundamentals of modern design systems, including Atomic Design, variables, design tokens, and theming.

    Through practical exercises, students structured a library based on atomic principles (atoms, molecules, organisms) to understand the logic of modularity and reusability. They then wrote the complete documentation for this Design System, including component usage, best practices, and consistency rules.

    The workshop combined theory, methodology, and practical application.

    July 2022 - January 2024 (1 year and 6 months)
    Boulogne-Billancourt, France
    Main responsibilities:
    • Design and improve mockups to optimize user experience.
    • Manage the design system for the mobile application, first as a designer, then as a referent.
    • Complete redesign of the Figma library: automation of variations, implementation of tokens, and integration of a light/dark mode switch.
    • Ensure graphic consistency and optimize work tools for designers and developers.

    Thanks to these initiatives, the design system became more structured and automated, allowing teams to work more efficiently while ensuring visual consistency across the application.
