About Bertrand

My role is to transform a business vision into a concrete, structured, and scalable product experience.

Whether it's for exploring a new concept (0 to 1) or revamping a historical service, I don't intervene for cosmetic changes, but to build systems that make sense.

Pragmatic and adaptable approach
I don't believe in systematic deliverables. My methodology adjusts to your urgency and your challenges.
  • In the exploration phase: User research, rapid prototyping, and concept validation to secure your product trajectory.
  • In the construction phase: Information architecture, complex flow optimization (back-office, expert tools), and robust Design Systems implementation.

Field expertise
Recently, I led the complete redesign of ViaMichelin for Michelin: a strategic shift from a utility tool to a "Slow Travel" ecosystem. I led the forward-looking strategy while mentoring a team of designers to ensure high-quality execution.

What I can bring you
  • Strategic synthesis: Translating business needs and technical constraints into fluid journeys.
  • Leadership: Aligning stakeholders and development teams around a clear product vision.
  • No bullshit, no "quick and dirty": Absolute priority on real user value and operational efficiency.

Available to support Startup Studios, investment funds (Design Partner), or companies seeking solid UX Lead expertise.

    November 2022 - July 2025 (2 years and 8 months)
    Boulogne-Billancourt, France
    Led the ViaMichelin design pivot — from a pure navigation tool to a more editorial, “slow travel” discovery experience focused on places and local curation.

    Had to navigate quite a few constraints along the way (legacy tech, ads model, business expectations), while still pushing for a meaningful product shift.

    Ran user research and workshops with product teams to explore and validate new directions, often through quick prototyping and iterations.

    Managed a small team (3 designers) and worked closely with leadership (CEO, PM) to keep design aligned with an evolving roadmap.

    Built a multi-platform Design System from scratch (200+ components), used across teams to bring more consistency and speed on the product side.
