À propos de Grégoire

Hi,

I’m Grégoire Méker, Lead Product Designer specialized in UX design, UI design, and Design Systems for web and mobile products. With 10 years of experience across Product Management and Product Design, I help companies structure, scale, and ship high-quality digital products with clarity and efficiency.

I work at the intersection of Product Strategy, User Experience, and Interface Design, supporting startups and scale-ups in building robust, user-centered solutions. My expertise includes:

- UX research, user flows, wireframing and prototyping
- UI design for SaaS platforms and mobile apps
- Design System creation (from audit to scalable component libraries)
- Design Ops and lean product processes
- Cross-functional collaboration with Product Managers and Front-end Developers
- Figma expertise (components, tokens, documentation, handoff)

I have built and scaled Design Systems and product experiences for clients such as Veesion, L’Oréal Tech Accelerator, Gorgias, SumUp, Criteo, and Mozza. My approach focuses on creating scalable UI architectures, improving product consistency, and accelerating design-to-development workflows.

Beyond execution, I help Product teams implement healthy lean processes: prioritization frameworks, discovery rituals, design reviews, and documentation standards. The objective is always the same: reduce friction, align stakeholders, and deliver measurable business impact.

If you need support on:
- UX audit and product redesign
- Design System setup or refactoring
- Mobile app UX/UI
- SaaS platform optimization
- Design Ops structuring

Let’s discuss your product challenges and build a clear, scalable design foundation.
