Eco Mode on — An alternative version of the site, optimised for slow connections and on-the-go browsing.

About me

I build modern websites. Simple as that. Custom-made, designed to fit your business rather than some one-size-fits-all template, using only the technology that actually serves a purpose. You stay in control of your site, with no strings attached, and I'm still around if your business grows or changes down the road. Based in Rennes, I also work with clients in Quimper, Paris, Berlin, or remotely.

My vision

A website doesn't need to be complicated to be good. Most carry far more technology than they actually need for what they really do. Strip away the excess, and you win on every front: speed, ease of maintenance, autonomy, and it ends up using a lot less energy too.
