Who am I?

From pixel to pipeline, I build solid web products.

Web developer specialised in PHP and the Symfony framework, perfectly at ease with HTML / CSS / Node.js, Docker and AWS.

Passionate about all things digital, self-taught and always keeping an eye on web news. I love drawing, sport and keeping up with what's new on the web.
