Some projects I’m proud of


3DVIA Home

I worked for 4 years for 3DVIA, witnessing its evolution from a small start-up to a corporate branch of the simulation software giant Dassault Systèmes. 

I’ve first been in charge with the complete restructuring of the price computation engine, which allowed me to work on many subjects from the data management to the UX experience. I especially developped the complex algorithms of price computation which had to handle laws from countries all around the world. My personal accomplishment was to offer real time prices while all other applications on the market required 30 seconds on demand. So fast that it even astonished some executives of Nobilia.

On a second time, I moved to the conception and creation of a 3D closet door simulator, improving my knowledeges on real time 3D rendering. It also allowed me to lead and train an outsource development in India, offering me my first real management experience.

Le Petit Gîte de Langon

Screenshot of the home page of the website

My most complete work as a freelance web developer/designer for the familial business of cottage rental. This website has been the theater of many experimentations to improve my web development skills but also my design abilities as it had to be perfectly functional, welcoming for potential customers and also easy to use by the owners of the cottage. This last challenge especially taught me to change my way of working with non-technical clients and offer more user oriented interfaces. 

On the technical side, I decided to work vanilla style using HTML5/CSS3 and javascript for the client side, PHP and mysql for the server. I also used JQuery for most advanced functionality (animations, AJAX interactions…). My goal was to push as far as possible my knowledge of the basic tools of web development.

I also worked on the design, producing all the graphic elements, and the SEO strategy of the website.

A little game developped in WebGL

WebGL is clearly one of the most important media of the future of 3D real time rendering. This is why I decided to spend some time studying it. What better form than a little video game to experiment with all the component of a online 3D application. Meshes, textures, lights, cameras, player inputs, optimization… the perfect pretext to play with all kinds of problematics. 

Work in progress!
