About Michael

Do you have an app idea, a SAAS to launch, or a business tool to digitize, but not a full team to design and build it?
I am a rare profile: I think product AND I deliver code. From UX framing to production deployment, I handle the entire chain, alone. You save time, consistency, and a lot of coordination costs.
Specifically, I design and develop:
📱 Mobile applications (iOS and Android)
📊 Dashboards, back offices, and internal tools
⚙️ Automations and integrations
🌐 Websites and business platforms
What I bring you: a product approach stemming from 30 years of digital entrepreneurship and a video game DNA (Ubisoft and Sony, on Rayman and Splinter Cell). I quickly understand a business, identify pain points, simplify complex processes, and transform a vague need into a concrete, fluid, and truly adopted tool.
Some benchmarks:
🚀 30 years of digital entrepreneurship
📱 50 applications designed, including children's apps with over 12 million downloads
🎮 Product DNA forged at Ubisoft and Sony (Rayman, Splinter Cell)
🏆 Famirelay, my platform for family caregivers, winner of the Made in 92 2026 prize and the Handitech Trophy, cited in Le Figaro
Technical stack: React, React Native, Flutter, Next.js, TypeScript, Firebase backend and Cloud Functions, AI and automation integration, UX design on Figma.
How I work: I often intervene after a brief discussion or workshop to analyze usage and friction points, then I propose a structured solution, quick to implement and managed through to delivery.
Ideal for: startups in the launch phase (MVP, POC), companies wanting to digitize a business process, or publishers needing an end-to-end product and technical partner.

    Famirelay is a mobile application dedicated to coordinating family caregivers. It helps loved ones who support an elderly or dependent person to organize themselves, share information, and distribute tasks, without getting exhausted. Winner of the Handitech Trophy and cited in Le Figaro, the solution was born from a field need and is built in direct contact with caregivers and healthcare professionals.

    As co-founder, I design and develop a large part of the ecosystem myself: mobile application, business dashboards, administration back offices, internal tools, and automations. I manage everything from product strategy to code, including UX and technical architecture. This daily practice feeds a very concrete approach: starting from real usage, identifying pain points, and delivering fluid tools that are truly adopted by their users.

    January 2022 - Today (4 years and 7 months)
    Paris, France
    Beyond my own projects, I assist companies in the design and development of their digital solutions.

    I act as a product and technical partner, capable of taking a still-vague business need and transforming it into a concrete, fluid, and truly adopted tool.

    My approach always starts from the field. I analyze real usage, identify friction points, and simplify complex processes before writing a single line of code. I am equally adept at framing a project upstream, defining specifications and user journeys, as I am at designing, developing, and coding it end-to-end.

    Mobile applications, business dashboards, back offices, automation, or redesigning existing tools, I adapt my intervention to the needs and business of each client. The objective remains the same: quickly deliver adapted, easy-to-use solutions that are truly used by teams.
