Feb, 2007

Until Aug, 2013


Carried out more than 20 customer projects between 2007 until 2012 to sustain my studies. Most of the projects were web-based, from wine shops to luxurious hotel. Design were made from scratch specifically for my customers while the websites were delivered powered by various CMS and frameworks.


On the shores of Lake Geneva, I have graduated from the Swiss Federal Institutes of Technology in Lausanne ( EPFL ). Interesting internship positions have notably brought me in other universities, like the Technion in Israël. During my studies, I was a teaching assistant for the courses of "Graph Theory", "Signal Processing for communication" and "Computer Network".

It is by forging that one becomes a blacksmith

About me

Proud father of a daughter born in 2022. If I don't have a rugby game during the weekend, I am probably rock climbing, or running. Because I am hyperactive, sport is essential for me to be able to work efficiently. Oh, by the way, sometimes I paint during work meeting to busy my hands to focus too. Here is some random pictures I took.

What about the blacksmith theme? When I was a child, I dreamed of becoming a blacksmith. In my backyard, alone, I was hitting piece of bright yellow-orange wrought iron to create beautiful shapes. Today, behind my screen, I am hitting the keys of my computer to bend line of codes to create beautiful interfaces. I became a websmith.
