I’m French, permanent resident living in Sunnyvale, California.

I love to share my design expertise which is my passion. I have more than 20 years of working experience and I focus on lead/manager positions.

Since 2016, I have the great opportunity to work for many startups in the Silicon Valley. I design high quality apps and websites, aiming to help people solve problems through creating an amazing user experience and a "wow" factor. Consistency and Simplicity are the two words defining myself. I also love to work on branding. I'm always the advocate of end users, often misunderstood by geeks/engineers.

I know how to manage a team with the right design tools and positive mind. I have experience hiring people. I'm still learning new things every day adapting myself to the American culture but I love to bring the "French touch" too :-)

I created this product for fun. I wanted to see live earthquakes on a 3D globe. It was very popular on the App Store during a time.

My Story

I got my first computer when I was 12 years old. A commodore 64. 
I switched after to Atari ST 520 and then the Macintosh II fx. I studied arts and letters and got my first job after school. I was very lucky to experience the evolution of design from the beginning of the digital revolution. I learned about typography and worked on publishing and advertising for many years.

I created my first company when I was 21 years old. I was building multimedia, interactive content when nobody knew about this word yet. I was using Macromedia Director. For a customer, we created the first CD-Rom to promote the Euro currency.

My second business was about internet kiosks with touch screens in public spaces. The company became number two in the French market. We were making everything: the design of kiosks and the content inside. We sold hundred of units to big corporations.

My third company was about building native apps for Apple platforms (iOS, macOS, tvOS). I worked on it for the last 15 years. The company was in the top 10 of French software companies for this market. We built an innovative project management application named xPlan and the first secure web browser for internet kiosks: xStand.

In my career, I had the chance to meet Steve Jobs multiple times at NeXT Computer Inc.

Technically, I'm an hybrid and open minded person. I have design skills and I know many technologies. It’s because I like to understand how things works. It's why I learned coding for websites. I can build almost any dynamic websites with e-commerce features and a database for the back-end but I prefer to focus on the design that is my true passion :-)

Design Process

This is how I work on most projects. There are always exceptions. For Apps, I prefer to build a prototype after step three in order to test the user flow.

STEP 1 - Goal identification

I work with the team to determine what goals the project needs to fulfill. I.e., what its purpose is. It's not always a simple task but it's necessary as most people tend to complicate things. This step is usually in close collaboration with the CEO or other stakeholders. If questions aren’t all clearly answered in the brief, a whole project can set off in the wrong direction.

STEP 2 - Scope

Once we know the project's goals, we can define the scope. I.e., what features the project requires to fulfill the goal and the timeline for building those out. It's often a question of budget or related to the size of a team. it can often lead to more work. At this stage, if the expectations aren’t matched by an increase in budget or timeline, a project can rapidly become utterly unrealistic.

STEP 3 - Wireframes

The team can start digging into the user flow, defining how the content and features we defined in scope definition will interrelate. It's very important at this stage to explains the relationships between the various pages and content elements. Although a wireframe doesn’t contain any final design elements, it does act as a guide for how the project will ultimately look.

STEP 4 - Content Creation

With the project architecture and some content in place, a team can start working on the visual brand, the identity of the product. It’s time to create the visual style for the product. This part of the design process will often be shaped by existing branding elements, colour choices, and logos, as stipulated by the company. But it’s also the stage of the design process where a good designer can really shine.

STEP 5 - Testing

At this step, a team have all content and defined how they display to the user, so it's time to make sure it all works. It's important to identify user experience issues before to launch a product. Errors may be the result of small coding mistakes, and while it is often a pain to find and fix them, it’s better to do it at this stage than present a broken product to the public. Launching too early is a common mistake.


I like these sentences from famous people. It's all about simplicity.

"Simplicity is the ultimate sophistication."


"In character, in manner, in style, in all things, the supreme excellence is simplicity."


"If you can't explain it to a six year old, you don't understand it yourself."


"Life is really simple, but we insist on making it complicated."


"Simplicity is the glory of expression."


"Beauty of style and harmony and grace and good rhythm depend on simplicity"


"It is vain to do with more what can be done with less."


"The ability to simplify means to eliminate the unnecessary so that the necessary may speak."

As I live in the Silicon Valley, I prefer to meet people to talk about projects and showcase my design process (most of my work is protected by NDA).
