He worked as part of a graphic design collective in Paris, winning a communications contract for Le Printemps de Bourges, which he worked on for four years. He moved to Brittany in 1995 and worked for various cultural organisations in the region, including the Brittany Symphony Orchestra, Mythos festival, Les Tombées de la nuit, Paroles d’hiver festival, Poche festival, Lanvellec festival and the British Film Festival.

He has also worked with Rennes 1 and Rennes 2 Universities and has created book covers for publishers Éditions Thierry Magnier. He develops partnerships with theatre companies (e.g. Label Brut, Théâtre du phare, Cie Forget me not, Cie Vis Comica) and dance companies (Fabrice Lambert), and he has designed sets for Cie Forget me not. In 2003, he founded the Le jardin graphique collective and in 2016, the tout reste à faire collective.
