Visual format that fits on all Screens platforms such as Mobile Phones, Tablets, Computers

Responsive web design has become more important as the amount of mobile traffic now accounts for more than half of total internet traffic.

Therefore, Google announced
(Since April 21, 2015) and started to boost the ratings of sites that are mobile friendly if the search was made from a mobile device.
This has the net effect of penalizing sites that are not mobile friendly.


Website Compatible with all current browsers such as Chrome, Firefox, Safari, Opera, Edge, SmartPhones and Tablets browser, etc ...

Because of the differences in the way Web browsers interpret HTML and JavaScript, Web developers must test and adapt their sites to work with multiple browsers.

For example, if a certain page looks fine in Firefox, but does not show up correctly in Internet Explorer, the developer may change the formatting so that it works with Internet Explorer.


Design realized mostly through CSS Techniques to ensure a great user experience.

Web design is very important to present your storefront with beautiful images certainly...
However be careful that it does not slow down your site unnecessarily at the expense of the user experience.

Standards such as trends, ergonomics, color codes must be observed to ensure the success of your website. Where the importance of using CSS codes to ensure beauty and efficiency.


The mechanics found under the hood of your website.

My lines of code are almost to ensure compliance with standards, it´s difficult to make a clear round when a website become complex.
By cons I just ensure you a smart designed code to avoid heavy Script related to the JQuery library, the many other needless or not optimized Scripts, frameworks that makes life easier for developer but are heavy, not very moldable and rarely fully mastered.
So I make sure to find the best methods through best pratice to ensure superior reliability, increased performance, Security, Fallback code for longevity.

Speed Matters !

Yes! But Why?
Speed is important for search engines like Google who will favor the fastest websites to assure better user experience.
That make sense...
Who like to wait ???

Therefore, it is important to take into account the weight of pictures, scripts and other elements that constitute a website.
Many Web Agency will offer you graphically stunning websites at the expense of performances and good coding.
Optimizations are essential to have the chance to be seen in the top ranking of Google search results.

What is the advantage of having a beautiful website if few people or nobody will see it?
And again it´s all about Search engine optimization (SEO).

Also to consider, the location of your web host and the amound of files HTTP requests (less there is, better it is)
between your hosted Website to the client.
Note this website is hosted in France so obviously it will take more time to travel if you live far away.
You can check by your self with
