Web engineering
Thirty years of full stack software development for the web: Nortel in Galway, AOL in Dublin, Liberty Surf in Paris, then the banks (Arkea), Naval Group, SME manufacturers and local businesses of Brittany. Today I mostly build interactive product configurators and calculators, the 2D and 3D tools that let a customer design a gate, a carport or a fence and leave with a quote.

Big data, big content
Some websites are made of content more than code. Since 2004 I have built expertise on content management and copywriting on various traffic earning projects.

20 years of experience on Wordpress does not mean this will be the tool of the future, but it has kept us going for a long time, still active on a few of the websites i've published.
Photography
Web design needs real pictures. After years of building sites, I came back to photography the digital way: a good camera, and the result on screen straight away, where film took days to develop. On erwan-foto.com you’ll find portraits of people and places around me, and the exhibitions I take part in, at events that mix visual arts, music and local life, in Locronan, Quimper and beyond.

Music
I started building websites in Galway, West Ireland, in 1995, and stayed there for the love of music : I arrived with a bombard and came back to Brittany with a wooden flute. Find out more about Dour Laouen, a musical project blending influences from Galway sessions and the fest-noz tradition of Kreiz Breizh, the Middle East Brittany.
