About Matt

Lead Product & Full-Stack Next.js developer, I help startups and SMEs design, build, and deliver their SaaS products from idea to production.

For 12 years, I've been working at the intersection of Product Management, UX Design, and Front-End Development (React / Next.js):

– R&D at Xerox Europe on products combining web & AI
– UX Design & innovation at Steelcase in an international context
– Co-founder & Head of Product at Tinkso, a no-code / low-code / AI agency (over 150 applications delivered for startups and companies worldwide, acquired in 2025).

What I can do for you:
– Frame and prioritize your product roadmap (Product Owner, discovery, workshops, backlog)
– Design the UX/UI and user journeys of your application
– Develop the MVP or the first version of your SaaS/platform in Next.js / React
– Improve an existing product (performance, UX, conversion, front-end technical debt)

Project types: B2B SaaS, internal tools, platforms and business dashboards, AI integration.

Based in Grenoble, I work 100% remotely, in French or English, with product teams, tech teams, or founders.

👉 Let's talk about your product: where are you today (idea, MVP, scale-up) and what's the next milestone to reach?
