UX Design

I'll help your users to fall in love with your product.

UI Design

I'll design the product that fits your users' expectations.


At an early stage, we prepare the mission with wireframes.


I can create an interactive HTML5 ready to integrate.

I'll Help You Design a MVP. a Landing Page. a Website. a Mobile App. a Desktop App.

I love to work on preliminary phases of a project. Feel free to pick my brain on your first ideas. A second opinion always matters while brainstorming a new concept. The first meeting is always free but, you have to offer a good coffee in return.

Why do I Dedicate my time on Startups ?

  • I'm passionate about entrepreneurship

    As an entrepreneur myself, I've launched multiple digital projects over the last decade. And I know the feeling of having the best business idea, but having a hard time to materialize it.

  • I love to think out of the box

    Being dedicated to startups implies having to think out of the box to be unique, and remarkable. I enjoy the challenge of having to diggest pretty complex matters in a simple, yet effective, User Interface.

  • Methodology Alignement

    Chances are big that your project will get remodeled several times before it goes live. Like many entrepreneurs I'm an Agile Methodology aficionado, I build products by iteration all the time.

Some of the latest projects

I'm using the best modern tools out there ...

So I don't lose our time on misunderstanding or guessing. The project is well defined, the feedbacks are crystal clear, the production is versioned, thanks to these tools.


Save Time, Money & Efforts

Let me work on your startup's new project so you can focus on things that matter. Working autonomously or together with your team, in French or English.
