I am Paul de Mercey, a web developer from France, settled in Tokyo since 2009.

I love to create graphics, design user experience and write pieces of code to glue those things together. By code I mean javascript and PHP mainly, sometimes I use a cms like Drupal, a framework (CodeIgniter, pureMVC...), or some other disruptive technology I like to try out (haXe).

On occasion I also draw graphic stories and when ideas are surfacing, I design small and simple games.
