Author of a book about HTML5

I co-wrote a book about HTML5 which covers a wide range of features, such as: semantics, microdata, audio and video, canvas, web sockets, offline apps, etc. The foreword is by Paul Irish, from the Google Chrome team. I also wrote a guest chapter in another book about HTML5, and an article in Web Design Magazine.


Initializr is my contribution to the community to make the web better by accelerating the creation of new HTML5 projects. It is the official custom build tool of HTML5 Boilerplate. Initializr receives a traffic of 42.000 visitors per month, generating 15.000 downloads, has more than 8000 Twitter followers, and a total of 2500 Github stars.

It comes naturally to me to explain technical topics clearly. My blog about front-end development,, receives about 20.000 visitors per month.

My most popular presentation, about CSS preprocessors, reached about 30.000 YouTube views, with a ratio of 98% upvotes.

Education and Languages

I have a Master in Computer Science from EPITA, where I learned programming, data structures, algorithms, UNIX, web and mobile development, and much more (mostly coded in C, Java, and PHP). I was a student representative, won an Android contest with the University College of Dublin, and organized the Open Source Day 2010.

I speak and write French natively, English fluently, and Spanish decently.
